We all know, if your car is modded, you see less then the stated HP gains. I personally saw, if I remember correctly, like 6 or 7 HP from the headers with HFC, and exhaust. If you were in my shoes, and saw first hand what stillen headers made on a dyno when dynoed the same day, and done correctly, and then someone else said they more then trippled your numbers, you would say NO Way! like I am. Like I said before, I only posted 1 dyno from a different machine/shop in my old thread and it was before most of my mods. Every other dyno was done at the same shop, same dyno machine. I remember you so well because numerous people posted the science behind how the pulley works, reducing mass, and how that can create more HP transfering to your wheels, and then I dynoed my car correctly with the pulley and got like 2 HP and you basically called everyone dumb, and a liar. needless to say, I'm glad you are doing this for the community, I'm glad you are happy with your numbers, I just wish people would take a step back and ask the question "how?" sometimes. Like you stated, surgeline is owned by cobb, that right there could be a big part in why you are seeing giant numbers, but maybe not. There are many other factors that can explain your giant gain with headers. What was the temp. when you posted the 302hp, and not the temp outside, I'm talking coolant and oil temp of the car? To get accurate numbers, data like this should be tracked. As your car heats up, HP drops. Thats why I asked before how many runs surgeline did to get the 324HP. I can easily see your car being ran hot and getting 302HP, then installing headers and going back there and running it cool and pulling 324HP with a tune. The facts are, we will never know what caused what, there are too many variables that factor in and were unaccounted for. Like I said before though, congrats on the numbers. But be warned, if you post somewhere on here that you installed intakes and with a tune you got like 30hp, you'll be hearing from me

P.S. Why go part by part with the tune? What was your baseline with stock ecu settings and all your parts installed, compared to all your parts and cobb's tune? That would be more realistic in what people with similar mods to yours can expect with a Cobb tune.
