1. The stock ECU has enough flexibilty to adjust for your current modifications.

2. Being that its an auto you will have to switch to something like the AEM stand alone to be able to change the redline. I'm not sure if Kpro will work with an auto. I have a stick and Kpro.

3. why would you want to change the redline down on an auto? The car will shift when if damn well feels like it. there is no changing that.

if you are hell bent on changing the tune you could always get an VAFC and do it that way.

I found that the stock Inj. will support up to 5psi of boost maxed out. Was bored and just wanted to see at the dyno.

okay thanks for the info. The reason i would want to change the redline is because after a certain point i can feel the power drop and it takes a while to get to the shifting point but thanks
