Denton S. from League City, whose F250 was in for an auto repair service, on 3/28/2016:
"First off...... These guys kick ass!!!! I've been to numerous shops for the last two years and have driven my truck for about 6 total months of the two. They went well above and beyond to resolve the issues I was having. I finally feel confident to drive this beast anywhere. Stephen, Art, Richard and Ken take a great deal of pride in the work they do. The "little touches" they put in my truck really sets it apart. LOVE IT!!!!!!! THANK YOU!!!!!!! Denton"

Larry S. from El Monte Ca., whose ford was in for an auto repair service, on 3/21/2016:
"As a fleet owner I look for ways to better our service department when maintaining our fleet of 6.0 powerstroke diesels. PSP Diesel has come up with some pretty amazing products for the 6.0 powerstroke engine. By using PSP Diesel's new aluminum oil pan with two cooling tubes for direct air to pass thru the pan. Has been a major plus with keeping our oil temps under control. We also run PSP Diesels aluminum Degas tanks in all our trucks. No more replacing the stock tank every two years because of cracks. The Parker/Raycor bypass total oil filtration system installed in our trucks will protect the engine from contamination that the stock filter will let pass thru. By filtering the oil down to 5 microns we are able to go further between regular schedule oil changes A special thanks to Art for all the tech info & recommendations that has helped to improve the performance of our 6.0 powerstrokes."

Marc W. from Traverse City Mich, whose F250 was in for an auto repair service, on 2/24/2016:
"Very satisfied with the quality of service and speed to which my truck was repaired. My wife and I were from out of town pulling our 5th wheel when we developed a transmission noise. After finding PSP on the internet with 5 star ratings we had it towed to PSP Diesel. We were giving a reasonable quote for the job and told it would probably be a couple days to finish due to work load. To our surprise PSP got ahold of us the next afternoon and told us they were able to get to us early and would be finished by the end of the day. One of the owners actually stayed late so that we could pick up the truck and leave Houston the next day. The other amazing thing was they did the job for a couple hundred less than the quote. Thanks PSP for getting us back on the road……Marc"
