"Took my truck on the road to east Texas for the second time since repairs and I am happy to report the truck:
* shifts much smoother
* More responsive on acceleration taking off from a stop
* More responsive on acceleration at higher speeds
* Gets 3 more mpg
I am very pleased with the level of professionalism at your place. You actually have QC which means a great deal when working with a shop. I will be back in touch in the near future to discuss more work.

Michael Lindsay from Alvin, whose F350 was in for an auto repair service, on 6/24/2018:
"My oil cooler was going south in my 2006 F350 6.0. I had already purchased a Bullet Proof kit to eliminate the stock oil cooler and move it to the front of the engine, (Old Style). I took my truck to PSP where Kevin helped set me up for the install. He took me for a tour of their facility and I was impressed as to how organized and clean the shops are kept. This is a great sign of pride in a mechanics work. A day later Kevin contacted me with a list of other items they recommend I have replaced. Now most people would say they were just trying to make an extra buck off me. Not the case here all of the parts had to come off when they did the oil cooler install so they did not charge one penny of extra labor for installing the new recommend parts. My truck was ready in just a few days and when I picked it up Art not only went over the truck and all the work they performed he and I sat down and talked for almost 45 minutes. Bottom line they treat you like family. They will get all of my business."
