My first time in and not my last. I have a 2012 F250 king ranch truck. I have had all my service done at the dealer and felt it was time to try something else. So glad I did. Went in for a oil change and mentioned my fuel mileage is poor. A couple hrs later Tommy called and said he might have found my problem. He sent the photo attached. My air intake is filthy. So I made an appointment next week to have that cleaned along with adding a new airbox and having the 9yr old antifreeze replaced. Update to follow.. so happy.. The dealer would NEVER find this and only wanted to up sell a fuel additive for my complaint.. Strong work men!!

If I could give zero stars, I would. My boyfriend took his truck here, and it sat for three weeks before they finally got back to him with a $7,000 estimate to fix what they claimed was a serious issue. Thankfully, we decided to get a second opinion. Another trusted diesel shop diagnosed the real problem, fixed it for just $1,100, and the truck is now running perfectly. After this experience, we looked through more reviews and realized we’re not the only ones who were misled or overcharged. Lesson learned, we really wish we had checked the reviews beforehand. We will never be coming back, and we highly recommend others stay far away from this place. In our opinion, they’re either completely incompetent or taking advantage of people. Either way, not trustworthy.

Excellent service. I received good advice on how to keep my F250 running well. The necessary repairs were done quickly and thoroughly. The staff was knowledgeable and honest, letting me know that some work I thought needed to be done wasn't necessary yet. Great service. Great staff. I will return.

I’ve used this shop twice to service my 06 Ram 2500. Both times they were very helpful and did the work with a quick turnaround time. While they have your truck they call and update you along the way, which is great when you need to plan your work schedule around your truck. The first trip there they replaced my Vacuum pump on my exhaust brake, a month later the part semi failed ( at no fault of the shop) I called and let them know the issue and they fit me right in and replaced the part for free. I recommend Diesel Performance Specialist and will continue to go there in the future.

Great guys and very knowledgeable. I’ve had some issues that they have made disappear. They have always kept me informed to the status of repairs. I’ll be back for sure….I own a Dodge.

If I could rate Diesel Performance Specialist six out of five stars, I would. When the air conditioning in my 1999 Ford F250 Super Duty started acting up, I brought it to Diesel Performance Specialist. They quickly diagnosed the problem, provided a clear quote, and had everything repaired within 48 hours. I was truly impressed by their excellent customer service and friendliness. I’m thrilled to know that Diesel Performance Specialist can handle any future needs for my truck, and I’ll definitely be coming back for all my truck services from now on.

I’m very thankful for the guys working here and the knowledge they have. I have a ram 2500 diesel that had a coolant leak and I took it to local shops in my area and none of them could figure out where the leak was coming from, long story short I brought my truck the Diesel performance and they found the problem and fixed it, feels good to have my truck back to normal and strong, everyone at the shop is professional and knowledgeable about diesel trucks, I will definitely be back if any other problems come up. THANK YOU Diesel performance team!!!

Ashton and his team did a phenomenal job identifying the issues with my electrical system and got me back on the road that afternoon. Very grateful for their timely and professional diagnosis!

Very disappointed with my experience here as I planned on doing a lot of upgrades on my 3rd gen ram I just bought. Wanted to get all fluids drained and refilled, complete all maintenance items, and AC was not blowing cold so wanted to get repaired. Made appointment and dropped off the day before. Called in day of appointment to check in and spoke to David. He said they were actually just starting to look at truck around 10am and he would let me know what's going on with AC and give me pricing. I called again at 3pm and David said they still hadn't looked at it. He then called me 5 minutes before they close, and told me I'd need to replace the compressor because it failed electronically and condenser and they there was no leaks. He then changed that to "well there might be a leak" and quoted me over $2500. He didn't bother to touch or address or give me pricing on any of my other concerns, and essentially just wasted the day by letting my truck sit there. I get things are busy, but I had an appt and he told me they were starting in the morning. I picked up my truck this morning and had David whining that he did everything right even tho my experience was terrible with him. I pulled my truck into another shop and they immediately found that there was a large leak causing the system to empty itself completely almost immediately. They also explained to me that if the system was empty, the compressor would never come on. So essentially David was either trying to screw me out of $2500 without even fixing the problem, or he was completely inept and they never even tested it. Either way, I'm glad I trusted my gut and went elsewhere. I'm really upset at this experience. I'm sure the techs and the shop are good at fixing things, but David has lost all the confidence from me to use them. Tommy seemed really great and he was apologetic for David's incompetence. If you pull into this shop and see David, just ask for someone else or try another shop if he's the only one there, since that is the excuse he kept giving me for his poor service. UPDATE: Went to another shop and within hours they had the AC system fixed for $400

I brought my diesel into these guys and was greeted well, given an honest evaluation, communication was perfect, the repairs were done same day and was charged very fairly. I would give these guys 10/5 stars if I could. Best experience I’ve ever had with a mechanic group.

I needed a complete engine replacement on my 2011 F-450. Diesel Performance Specialist did an excellent job at a fair price. The communication throughout the process was awesome. I'm very satisfied and will recommend them to anyone.

Very professional shop. Communicated everything needed for my truck that was critical verse discretionary. Cleaned up inside my truck after extensive service on about $14k worth of different systems in my 2016 Ram 2500 with 153k miles. Haven’t done much to this truck for service thus far other than what’s recommended so it was time to get some things handled. While they aren’t the cheapest in town, they clearly take their time, don’t cut corners, and pride themselves on quality work. I prefer to pay a little more and actually get higher quality work as opposed to paying more and getting poor workmanship. Had my entire coolant and heating system serviced and replaced, air bag compressor in the back for my air ride system, gear box for steering, EGR valve and thermostat. Highly recommend

Recently had a full inspection on my older BMW that led to a few substantial repairs and routine maintenance services. Communication was excellent and I am now confident that my beloved Beemer is in good working condition. My thanks to Joshua and Dennis for their excellent service. This is my go to shop from now on.

I had previously taken my 2020 F250 Super Duty to 2 other shops for steering issues. I spent a couple thousand dollars trying to get the steering right with little success. It was very frustrating and costly. I found this shop on Google and decided to give them a shot since they specialize in diesel trucks. I dropped it off on a Thursday and it was ready on Friday morning. The cost was a higher than I had expected but not outrageous. After driving it home I quickly realized it was worth it. After a year of failed attempts to make my truck drive right, they have fixed it! My truck drives better than it ever has and I feel safe driving my family in it. Thank you DPS for your great work!

Diesel Performance Specialists were a life saver. I did not have an appointment with them. I drove from my house to another appointment located in the same parking lot as their business. Once I arrived, my car started to produce heavy steam from my hood. One of their technicians offered to look at my car. Not only were they able to diagnose the issue quickly, but they had the problem fix by the end of the day. Their professionalism and service has gained a new customer!

First time using Diesel Performance. The location is local to my home which was what drew me to use them. Once I made my initial call and spoke to David about my truck issues, he was quick to help me and his knowledge of my truck solidified my decision to use Diesel Performance. The repairs were nothing short of timely and as expected. Communication throughout the process was excellent. I’ll continue to use Diesel Performance for all my truck needs. Great experience!

Dennis, Dave and the folks at DPS are awesome and treat you like family. They are extremely knowledgeable about the vehicles they service, they do what they say they are going to do, and have an awesome warranty for the services they provide. I could not be happier with the service I received. If you are looking for an honest, knowledgeable, friendly deisel repair service give DPS a try. You won’t be disappointed.

It takes serious service (or a lack thereof) for me to take the time to write a review, and David and his crew have earned a 5-Star review hands down. Nice folks, welcoming, and professional. They were amazingly helpful in diagnosing an issue my truck’s dealership kept blowing off and one they hadn’t even identified yet! I’m stuck with the dealership for most issues right now as the truck’s under warranty, however DPS now has ANY of my diesel-related business outside of what my factory warranty mandates the dealership handle!

These guys are the best diesel shop ive dealt with hands down. I own a duramax and had them work on it a couple times. There always quick to get my truck on a tow truck, and working on it. They are quick to get it back up and going. The staff is very is helpful. **** I was down in rocklin looking at a job for our company, and ended up getting our pickup stuck. I couldn't get AAA to come quick enough to get me out. So I reached out to these guys who were 10 min away from me. (Mind you they are a diesel shop, not recovery lol) They came out anyways and yanked me out. Thats customer service!! They wouldn't accept a tip either. These guys will forever have our business!
