What type of gas are you running? Exxon shell QT? Tuner told me to run QT I'm assuming because it has 10% ethanol in the fuel. From what I've been reading ethanol has a higher octane rating, so it supports a higher compression ratio and more aggressive ignition timing. So I'm hoping with this...

Sorry if this question has been asked before but i don't have a lot of time to find the answer .I've noticed a lot of people running 1-7/8 instead of 1-3/4 header on the 15 GT. I was told on a N/A car 1-7/8 header may be to big and you may loose a little torque and power. 1-7/8 headers are for...

Ok here's what I'm getting about exhaust. Cat back don't make any horsepower, more sound then anything else. But what I'm thinking is that the cat back on the stock gt is so restrictive that adding an aftermarket cat back will free up some horsepower. Is this correct? Did anyone dyno the car...

Whats the difference between Kooks long tube headers and Sainless Works headers beside the price?. Kooks is about 300 bucks more. Also does the cat back add any horsepower or is it just mostly sound? Should I get the 1 7/8 or the 1- 3/4? Im guessing the 1- 7/8 makes more power? Thanks

Car made 410 at the wheels with a cold air and tune. Tuner said computer or engine was taking the timing out of the engine. Said it could be something with the fuel that I filled up with. Does that sound right? I didn't use shell I used exxon supreme. Another question is 410 a good number with a...
