Thanks Steveo! As soon as i completed the upload and cranked it over it sounded a whole lot better, idle went from a 550-ish RPM to a 750-ish RPM, seems like the perfect idle now. took it out on the main street and man O' man what a difference..like night and day ,awesome feeling after it sitting for 15 yrs. Although the 4L60E w/shift kit, shifting seems a little strange...IDK...a lot of torque? maybe the 3:08 gears??? i heard that it probably needs to be more of a 3:42... but man what a feeling
