My company Superformance, www.superformance.com and Hillbank Motor Corp. www.hillbankusa.com are having an open house on May the 10th, we will have a dyno day here where you can have your car dyno'ed.

It is $50.00 the first pull and $25.00 after that i need a stock X-fire to compare mine with. i have the needswings intake and the magnaflow cat-back i want to know how much more it makes over stock.

So all in all i want to put my car against a stock one on the same dyno on the same day to get a very accurate read on it.

Any help would be much appreciated.

I would prefer a manual.
