FastHouse Performance Diesel

I do not recommend allowing this shop to work on your diesel truck. I brought my 2008 LMM Duramax to them for installation of a turbocharger, intercooler, and hard piping. After picking up the truck and driving it home, I inspected the work that had been completed and found numerous serious issues. The intercooler and radiator crossmember had been cut out with a grinder instead of properly unbolted. Transmission fluid was leaking heavily.

Great shop, good prices, wheel bearing was going out, lady in the front was very polite and helpful, supervisor offered to take a look at it and wasn't even gonna charge me for that, we saw the faulty bearing and this guy Bubba dropped whatever he was doing and knocked the job out quick...

They guys were able to diagnose and sort out a tuning issue on my pick up that two others were unable to make progress on. Got it back to running as it should in a very timely fashion. Brought my pick up in from 3 hours away because having guys that were confident and knowledgeable about the motor in my pick up made me feel more at ease than local mechanics just guessing/throwing parts at it. Very pleased with there work and will definitely use them again and send others there way.

Where do I begin, I came to Austin and Fasthouse with a truck that needed some fixing due to a previous shop doing a hack job on her. The guys were quick to diagnose the issues I was having with my ac and drop my new turbo and fass fuel system all within a couple days. The lady at the front desk is very informative and eager to help and update. I’ll never look anywhere else for diesel performance, they got my L5P running like a bat out of hell. Forever customer.
