The first time I brought my truck in I got EFI live and the tunes were great, everything that was expected. Later on down the line I got my headstuds, headgaskets, FPR, EGR delete, and a bigger set of 5 tunes and man did they give me a smokin' deal! They also got it done in a very timely fashion and haven't had one problem since. I also got my stage 4 allison built here and they run a crazy cheap special of 3850 out the door (it only took them 2 days also!) My truck is so smooth now and at the same time has power that is consistent. No BS here with any of my service or the quality of the work done. Pretty soon I am looking forward to them putting a lift pump in and turning my duramax into a 12 second truck! I will always call these guys for parts and service and I would recommend any one to them. They are very confident in their word and take alot of pride in everything they do. I really can't thank these guys enough for what they have done for me!

I called Underground Diesel Performance, they sent a truck and the next day i was back on the road. Turns out my bands were out of adjustment on my 06 Dodge. Ended up spending $200 when i thought i was going to spend thousands. Excellent service, clean shop, great guys! Adam
