mine is an 86.5 according to the door. yes it was stock turbo i just made it stick. i have tested the intercooler pipes a couple of time and no problem. my gauge never drops wile i drive it actully hits 15psi in 5 gear no boost cut still trying to figure that one out. thanks for the info on the ecu if your correct i guess i dont need to buy one?my trap was only 94miles/hour. lots of wheel hop of the line. couldent get another run in to correct it.
