I was having a turbo actuator code failure. Normally, I would have dug into this myself, but time was an issue for me. They diagnosed and fixed my truck in 3.5 days. Communication and service were great. Had an Oil change while it was there, and the RAM is running great again! The pricing was as expected but fair.

They did a great job. I did a lot of price checking with other companies and they outpriced them all. I will be back if I need to be.
