i have a greddy turbo kit and just tightened up the wastegate. i've been running 5.5 psi (thats how it came), and i want to go to 7 psi. so i tightened it all the way and took it out for a ride. i peeked at 7 psi, but it dropped and held steady at 6psi. is there a simple solution to get it to hold at 7psi? thanks
oh yeah, i fixed a boost leak the other day and it is still dropping off just a little bit when i hit vtec. i never noticed it before, but i also was never looking at my boost gage when i was in vtec until just recently. is this normal for the greddy kit?
