Thread: 3.4 Pulley

In order to benefit from all of those items on your list you will need a tune. The more "hard parts" that you put on, the more KR you will likely have. KR is a reduction in timing due to the engine sensing knock. KR = loss of power. A good tune will help decrease KR if not totally get rid of KR.

A tune is where it's at!!

Truly I would hold off on installing your parts until you get either a tuner or get with someone on this site that is near you and willing to help tune your car. A tune in my opinion is so important that if you put on these parts without a tune, you could end up having a lower performing then stock car. This is due to the KR. Remember KR takes away timing. Timing is power.

That is a good list you have tho...I would get those, just don't install until you get the ability to get tuned.

It sure will.

with headers you should be pretty good, but youre going to at least want some type of PCM upgrade to go with that stuff. 6* of knock WOT is not a good number, which is where youll be with a bad tune if youre lucky.
