Russ and his team put together a complete picture for each cutsomer. It can be complex and intimidating to start upgrading, but they are professional and thorough and totally worth the investment.

Can't say enough positive things about Powerflo and the team working there. This is the second truck I have taken to these guys and they do great work. They are also very honest with you on what should be done and how it should be done. Or in my previous trucks case, what I shouldn't repair even though the repair bill would have been very high. Appreciate the honesty and good work.

These guys are great. Recently replaced my body mount bushings and the truck is so much better I can't even describe it. They've done work for me a few times in the past as well. Their work, large or small, is handled reasonably quickly, but more importantly is done right. Nice people too. I like working with local businesses like these that do a great job. They've earned my business and I'll be a repeat customer until they don't want me.

Great diesel mechanic. Very good quality work. They fixed a hydro lock for me, injector issues, ran tests and threw in a new KC turbo package. My truck runs way better now, sounds great and much healthier with the injector clacking gone now. Knowledgeable about their trade even older diesels and they only uses the highest quality parts. Nick was great to talk to, and I appreciate the time he takes to explain things plus the good pointers and the questions he answered for me. Also the whole team as well by keeping me updated thru the repair process. A+

If I could give them more than five stars I would! Nick, Russ, and the rest of the guys in the shop are AMAZING! They’ve worked on my husband 6.7L f250 and my 7.3L excursion and we have been beyond satisfied with them! They are super knowledgeable and will explain everything in detail what is wrong with your truck, they’ll tell what needs to be fixed right away and what you can hold off on. Definitely will keep bringing the trucks back! :)

I can not give these guys enough stars. Russ and Nick are exceptional guys along with their whole team. They always have my Ram running at top performance and I haven’t ever found a more honest and straightforward shop. They are very easy to work with, they get the job done timely and done right the first time and that goes along way in my book. It’s a true pleasure to work with these guys and I would recommend them to anyone that is in need of any kind of work on their diesel truck. Thanks you guys for being top tier in your work and customer service. It is greatly appreciated.

5 Stars - Honest, Fair, and Outstanding Service I recently took my truck to the team at Powerflo Diesel, and I couldn't be more impressed. From the moment I dropped off my truck, the level of professionalism and customer care was exceptional. They provided a clear, honest quote and kept me informed throughout the entire process. What really stood out was their integrity. After getting a full turbo replacement quote from the dealer's service department, these guys were able to identify and fix the real issue at a fraction of the cost. They saved me a significant amount of money and didn't try to upsell me on unnecessary repairs. If you're looking for honest, reliable mechanics who go above and beyond, look no further. Highly recommend this team for anyone needing diesel repair! God Bless the team at Powerflo!!

Russ and his team are amazing to work with! Unfortunately, I’ve had to visit them a few times because my truck likes to act up, but it’s always a relief knowing they can get me back on the road. The first time I brought my truck in, I knew they were the best when I got an overpriced quote from the dealer that didn’t seem to address the real issue. I’m glad I didn’t go with the dealer’s recommendation because the issue they identified wasn’t what was wrong at all. Russ and his team figured it out and got me fixed up right!

I had Powerflo give my truck a lift and install new wheels. They were great. Absolutely no problems. Truck looks and rides great. And they stuck to the original quote for all the work. Thanks Powerflo!

Just wanted to shout out to the guys at powerflo. I've had bad experiences at other deisel shops but not at powerflo. They kept me informed every step of the way on the progress of my truck. And I couldn't believe the fast turnaround on getting it back. This is a top notch shop that anyone should feel comfortable with leaving there truck for service. If you need anything done to your deisel truck, this is the place to take it. I'm a customer for life after the service I was given. Thanks guys. Jeff

Russ and Nick are great! I’ve had several trucks serviced there and they always do a good job and I’ve never had to take anything back. They do it right and they do it well. Would recommend 100%.

I’m gonna be honest I have that long and hard about leaving this review because I want to believe better in people but I brought my F3 57.3 L in here a few weeks ago I think it’s probably been about three weeks now I was having a problem with it, randomly shutting off while driving And then after a brief period of sitting, it would turn right over like nothing was wrong and overtime this began to happen more frequently so I finally took it to this diesel mechanic They run diagnostics and it comes back that it is an IPR sensor and that affects the oil pressure which can be a reason why it shuts off now I am not a mechanic so I do not know everything about trucks but seeing as that is the case it has led me to feel even more Compelled to leave this review because once they did $4600 worth of work to my truck, I brought it home and it continued to do the same thing so I got on ChatGPT and I type in the symptoms and what comes up well what came up in the number one position was the camshaft positioning sensor in the number two position came up the IPR sensor and then in the number three position, the camshaft sensor was mentioned again so I go to O’Reillys I buy a $35 camshaft positioning sensor and me not having any mechanical experience at all. Installed the new one in less than 20 minutes now if I were a diesel mechanic who had been working on diesel trucks for over 20 years of my life, I feel like I would have at the very least seeing that it could have been the camshaft positioning sensor to start with I would have changed it just in case I know it didn’t throw the code, but it’s a very cheap part with minimum labor and I would’ve just thrown it in there just in case it fixes the problem, but that is not what power flow did. They went ahead and chose the most expensive option which granted it did throw that code as far as I know, I do have a printout showing that it threw that code But I can’t help to feel like maybe just maybe that those computers can be manipulated and given the situation in our current economy it would not surprise me that they chose the more profitable fix than the $35 fix So as a word of warning, please run your symptoms through ChatGPT And try to get a little bit of an understanding of what possibly could be going on with your vehicle. I very much regret that I did not do it in the first place and that is on me, but I do feel like it is their responsibility to be as honest as possible, and help their customer as much as possible.

Just bought a LMM duramax with efi live, well previous owner didn't know what the tunes were. Called this place and the guy was outstanding on customer service. Most people companies suck with customer support service because they not making money but not this company. Guy simply said I cant tell you the exact tunes but could hook up and tell me what they are labeled as. Then proceeds to tell me if I cant bring it in he explained how I could do it myself. Im not from this area but if I were this would definitely be a shop that would have my trust. Keep up the great team work!!

I installed the fuel filters myself, and couldn’t get the truck to start even after priming the lines several times. Powerflo got me in first thing the next morning, and quickly discovered that I didn’t tighten down the fuel filters to spec so air was getting into the system. Now my truck is running like new again. Thanks for your help at the last minute. I appreciate your honesty and integrity. Powerflo Diesel saved our vacation!

Great service and good communication from these guys. Had my Ram 3500 in for a diagnostic at 265K miles and they did an awesome job on it. They ran the diagnostic and just sent a list of things needed, not upsold or pushed. Replaced engine breather filter, differential pinion seal(a pain to do on your own), Removed and replaced track bar, and a much needed alignment. Truck was ready when promised and runs great. Thank you so much!

Project Completed - Hard to believe it’s been 3 years since I first showed up at Powerflo with the “gifted” 99 F250. Over the past 3 years we have replaced or upgraded most everything but the power train. Survived a traffic accident that destroyed the bed and front grill and bumper. Total spend has been about 25% of what a new F250 would cost and no 7.3 engine. The last phase was upgraded radiator, intercooler kit, transmission cooler kit, and hydra chip. It totally changed the performance of the truck and it is super responsive. Russ and Nick, mostly Nick, sorry Russ, have been along for the entire ride. Thanks guys for making the restore so rewarding.
