Used him for my 6.0 took a very long time to get back. When i got it back the programs were all messed up. He new a that power steering hose was getting pretty wore and didn’t say anything 2 weeks later left me with a leaking power steering hose. Have been trying to get new programming for the last 4 months. Have been very frustrated with everything he has done. Won’t go back.

These guys are the real deal, straight forward, excellent mechanics, no bs. The owner always had time to fully explain necessary repairs with timely updates on progress. Prior to bringing the truck in Sam spent a considerable amount of time discussing how the truck was acting. When I picked it up they went over all repairs and discussed maintenance of installed systems. They are extremely knowledgeable and way better to me than the local Ford garage.

I read a review on FB about his work for another customer. At that time I was searching for a new "trustworthy" diesel mechanic. I took my 6.0 to him with a transmission that I thought needed to be replaced. I'm still running it, 20,000+ later. I asked him to check things over while it was there to make sure everything else was right. FICM was zip tied, turbo bolts were missing and up pipe clamp wasn't seated properly and was leaking. Oil cooler numbers were close to being condemned so he did a coolant system flush and external coolant filter. He found autolite glowplugs and replaced them. Needless

Thank you J&S for the great Ford 6.0 Powerstroke products! I purchased FICM programming, ArchOil AR9100 Oil Additive and ArchOil 6200 Fuel Additive. I definitely noticed a big difference with the FICM programming. Starts alot better cold. Better throttle response. A little more power. The same trip I average 13-14 this tank average around 15.5-16 No more Injector shudder or missing anymore either.

I have had two of my 7.3's worked on at this shop, always pleased with the results. Sam always keeps me updated through the process letting me know what could use attention while it's apart. (Saving the labor costs of having to rip it all down again) Family members and friends of mine have had 7.3's and 6.0's done at this shop, both of which were impressed. If you're looking to increase performance or just make your truck solid J&S is the place I'd recommend.
