You will really only get about 5-10 depending on what else you have done ie exhaust, intake, heads, cams. You will feel SOTP hp because of the better throttle response.

This upgrade is really only good to improve the performance of other parts.

And after the exhaust is done. With a stock exhaust, you see virtually no change.

A n/a car will see about 5 rwhp while 15-20 rwhp is possible on a s/c car. You can see dyno results of different brands in the Tech sticky at the top of the 4.6 forum.[sm=smiley20.gif]
