Greg M. from Friendswood Tx. 77546, whose F250 was in for an auto repair service, on 6/3/2019:
"I retired from Caterpillar as a technical Communicator for many years, I've worked on the small and the Big Cat engines. I have problems with my 97 7.3 low power pulling my large travel trailer I felt that 394000 Miles might have been the issue until I talk to Richard Martinez one of the owners at PSP. He suggested we try the Edge resolver performance chip switch. The travel trailer gross weight 12,394 lb, at 70 miles an hour 2200 RPMs I still have plenty of power. Thanks to Richard, Art and the PSP crew the old 7.3 is not dead yet at 390,000 miles. The service was impeccable I called on a Monday and was rolling down the Highway within a couple hours.👍👍👍👍
Thanks Richard for your knowledge on the 7.3.

"I had a complete rebuild with upgrades a almost two years ago and really worked my truck. I had developed a couple of oil leaks and was in the area so I dropped bye PSP in South Houston and the owner Art was there,like he is everyday. Well he was not happy. To make a short story shorter,Art warrantied my truck and fixed the leaks. So if you want to talk about honesty and integrity. you lead bye example an that is definitely an example. No one but them will ever work on my truck...."

"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.
