Are you running the stock frame setup with the Internal wastegate or the stealth kit with the external wastegate? Just curious if the stealth version would gain more power I have the 3582r kit. Nice numbers I think that's about right for the 3071.Where did you end up at peak boost?

its the ATP stock location , internal wastegate. I would love to get away from the stock location. Tuner told me 27 psi, although ive seen it spike to 32 then come down to 27 .

With your final drive and the 2.3 that will be a monster on the street. I bet it pulls real strong. I have a 4.08 final drive but want to build my bottom end before I send it.

It does, to me it feels really fast. Fun on the twisty windey roads as well. You will like the 4.08 FD

Do you have access to e85? I'm getting used to the fd coming from a 6 speed trans. Its wierd you feel like you are not accelerating and then you look down and doing 120 lol. I love how I can cruise at 80 at 3000rpms.

do you think the bigger exhaust helped with back pressure contributed to making the extra hp and what were you making previously?
