Can anyone recommend a garage that I can take my PSD for a checkup. I don't believe it's running to it's potential. I need a shop, prefereably with a dino, that can check everything out. They must not be parts changers and must know what they are doing. No dealers. I think I am asking the impossible but I figure it's worth a shot....What the heck, it doesn't cost anything to ask........... Thanks ...

 

I don't know anyone that has a dyno but if you're looking for a good shop, superduty headquarters in mesa (might be gilbert, it's on close) does some good work (know from past experience). Those guys know SD's inside and out, gas or diesel.. You might try giving them a call.
