i have installed...

trifecta tune
aem cold air
jet mass air flow sensor
bosch iridiums
trunk weight reduction
magnaflow exhaust(just the muffler)


just give me a number off the top of your heads...

I'm guessing you have a 2.2l?
140 stock at the wheels considering a manual trans, you might of gained 5 for the tune and 2 for the intake...
147 at the wheels is my guess? 170whp if you're a GT 2.4l?

fyi, that muffler, the spark plugs, and the weight reduction are not really changing your power output

Sounds about right

yea if ur a 2.4 i would say at least 170whp. all i have is the gmpp catback and the k&n intake on my 2.4 and i dyno'd at 167.7 whp.... torque blew but im sure a tune would help that. i bet ur gunna hear a lot of this too, but if you're really interested in power forced induction is the way to go man :twothumbs
