Are today's tuners on diesels reliable and trouble free? If properly installed, does more power negatively impact the longevity of a properly maintained engine? Thanks in advance. Mike
Thanks, everyone for the responses. Other than a Ford Severe Duty AIS system and a Brian's Truck Shop built transmission, our 20002 Ford 7.3 with 180K is stock. It has been a wonderful, trouble free truck.
However, it sure would be nice to have a little more power towing our little 5500 lb travel trailer and have no downshifting on small hills.
Guess me and my bride of fifty years will be looking into a tuner at some point.
