Customer Reviews
Chris Y. on 12/4/2015:
"I have been meaning to give you a report on Clifford's recent trip to New Mexico. He performed better than he ever has before. The temperatures are now running 15 degrees cooler than they used to and I never saw more than 210 on a steep grade. His power is improved making it safer to pass and easier to drive.

The combination of the turbo blanket and the turbo pipe wrap has quieted the interior noise and the temperature of the dog house is much-much lower. In the past you would almost burn yourself on the passenger side of the dog house but now it only gets slightly warm.

The van always started easily and the mileage is now consistently in the high 14's as compared to the mid 12's before you worked on it.

Overall I am very happy with the performance and improved reliability.

"Great service, both Mitch and Bobby are very knowledgeable when it comes to Powerstroke engines, after visiting other local shops, I decided to give my 2004 F250 another chance, couldn't be happier, truck is running better than ever before.
Thanks East County Diesel.

"Don't know the experience of others but Bobby did a great job getting my truck back up to snuff after two years of sitting. It runs great. BTW, a senior Ford service manager at El Cajon Ford is the one who recommended the shop since I had several upgrades to be dealt with. It's been a couple years now and I still go for oil changes, etc."
