PCM reprogramming


  

altrestle -> PCM reprogramming (1/5/2007 1:51:34 PM)

I was thinking of having my PCM reprogrammed.  What are the good things to expect and the bad things.  I have read on the forum something about error lights that need to be reset.  I am looking of ways to increase power and mpg.  I already have installed Borla exhaust.  I am thinking of ordering the air raid throttle body and  K& N filter system.
