For a quick run down before I post the dyno sheet. The first time I had my car tuned I had Stillen G3, GTM test pipes, and Greddy TI-C exhaust (silencer removed). Take note that on Forged dyno (dyno dynamics) it reads lower than most dynos. I'll give a reference shortly. Anyways the first tune I put down 292whp with the above mods. Then days later I put 310whp on Z1 Motorsports dyno (dyno jet). So that gives you a reference of the difference.

Well today after installing Momentum Headers and retune we put down 316whp. So that's 24whp since the last tune. So that's a great gain from headers alone. Definitely the best headers on the market and the price makes it that much more pleasent. I have a good feeling that on Z1's dyno it will put down 330whp+. This is about the only mod I've ever done that I've actually felt the power increase.
