Ok so I'm stage 2 full invidia turbo back n1 race and aem cai. I have a Cobb ap. So I went to Cobb and downloaded their aem stage 2 tune. Did some Guage watching lol and realize I'm only making around 15psi. Is about 2 psi from what they say so I downloaded and flashed Cobbs high waste gate. Did some test pulls and it peaks around 18 psi... Well it looks good but the car doesn't like it and bogs hard. I was wondering what's yalls opinion on what do to. What sparks this thread is because my buddy just got a new motor put in and is running the Cobb stage 2 with the Cobb short ram intake and he can do a pull at 19psi. But the weird thing is, is that the car has no bog is a smooth gradual increase in boost in 5th. So what is it that makes his so much smoother? Is it the short ram or what? Should I try his tune?
