I had some changes made on my stock tune (leaned it out a bit) when loading a Lund or VMP tune do I need to take it back to the stock tune before loading? I'm adding a JLT and cj65 throttle body. Thanks in advance for your help.
Any thoughts on what would cause the BMR uca bushing to split and go bad on a 14. Went to road Atlanta and Sebring. It went bad after the second session at Sebring.
