Agreed on the boost controll part… its not all boost thats the problem. I know this, but its the easiest thing to adjust with the proper tools/equiptment, without using highend tuning and other means of governing the tq produced at different speeds. And nobody wants to run around on a slick on the streets. so lets just quit the slick talk. we are in the SR section atm. :thumbup
and i honestly dont see you being able to hook 1st, or even 2nd with simple foot controll. and when you say 23psi thats max I assume. no way did your car see 23 psi in 1st or 2nd gear… its false advertising. unless your fluttering the gas pedal like a mexican hat dancer there is no way to limit the tq produced in those LOWER 02M 1st/2nd gears to make it hook.
I might go out and log throttle position/actuall boost/engine rpm and vehicle speed. I Bet 35% throttle input will show wheel spin in 1st and 2nd.
