silverss05 Posted November 27, 2006 Report Share Posted November 27, 2006 Which would be a better thing to get done at this point in time. A shift kit or a PCM tune? I am planning on getting my exhaust redone with edelbrock shorty headers going to dual Flowmaster super 40's out the right side and i have an AEM Brute Force intake. Also if i do a shift kit do i need to do the TC? I heard the TC takes a toll on the MPG? thanks for all the help. Quote Link to comment Share on other sites More sharing options...
rivierakid55 Posted November 27, 2006 Report Share Posted November 27, 2006 i think they will both compliment each other. i can tell you that i did the shift kit first with no tune as the new 06 pcm's were still on order and i couldnt believe the results. but when i added the tune to go with it, it was a whole new ballgame. i think there are others who have just done the tune and are happy with it but i believe to really get those really really firm shifts i think you need to change hard parts (i.e. springs, servos, etc) in trans to do so.
