well i only have it set very conservatively, IMO this is how it should have come from factory. still hardly smokes at all, but torque is impressive compared to stock. you can see it in the boost it makes. to get 10psi was before around 2250rpm. now is 1700-odd, max boost is 16.5psi at 2500, verse 14 before (still running turbo without wastegate).
main reason for conservative tuning is i havent figured how to adjust the idle, which is now a tad high. soon as i figure that, its getting turned waaaay up... i wanna be painting the pavement black behind me
oh yeah and as i said, if you dont use the extra power, your economy will improve substantially.
