ill try to make this brief, overkill pcm was tuned for me when my gtp was stock, the new setup will be headers/rockers/3.4/catback/intake. until i am able to get it custom tuned on the street is it WORTH IT to send my pcm back in to get re tuned?
is my current pcm holding me back since its tuned for a stock 3.8 pulley or not really? they no longer lock the pcms so its a solid base tune to go off of if not anything else

input please
