Hi guys I have an 02 5.3 avalanche and would like to get some help on custom tunes for performance with SC. I have the SC preset performance but my wife seems to think that the getty up off the take off is actually worse then stock. I feel the difference once I get to the higher #'s but feels strong not fast ifthat makes sense? PLease help :laugh:
