My 2010sti made 262hp on the EvoR dyno @ 20pound with
tbe/grimmspeed bcs. I shit my pants when I saw the numbers. I wasn't happy at first. But the numbers are what they are, as it has been said all cars respond differently.
I love the way my car drives now, as for the high psi, we'll just have to wait and see.
Take it back to the tuner if you're not happy I'm sure they will help you out. ASG has a good reputation.
