sorry but this doesn't even make sense to me
"the car comes on full boost at 3000 or just over, and then as soon as it hits around 4-5000rpm, it just climbs all the way to 14psi, even with the boost contrtoller removed and having a boost line from the acutaltor the intercooler pipe, it still does the same, but as soon as it hits 6000rpm, a big rush of power comes, so fast that you dont have enough time to change gears before it redlines. "
what does it do between 4K and 6K ? lose boost? spike? lose power not boost?
got a dyno sheet with a boost or AFR map for this issue?
