So i recently picked up a used whipple throttle body and put it on my 13 GT500 which still has the stock supercharger on it. Then i had lund tune it and the car always has a very high idle after running it hard the rpms go between 1000-1500. Lund cant seem to find anything wrong with the tune, i was wondering if any of you guys have had this issue and what you did to fix it.
Thanks everyone!
