Ok It dosn't matter where my MBC is set if I give it full throttle it will kepp boosting till I let off like 20psi. aT IDLE IS A -20 IF I DRIVE THE CAR W/O GIVING IT FULL THROTTLE and go to 10 its fine but still feels slow. But here is the part that pissis the living Sh*t out of me. If I give it alot of a gas the boost will hesitate I here a popping sound threw the exhaust and the boost skyrockets to like 20 22 even!!! on stock injectors. I don't want this problem and longer I just want to boost like 17 steadily. I will check my inter cooler for leaks tomarro but I doubt it.

I need help DSM'ers thanks,
Josh

I've got the exact same problem. I did find some leaks at my EGR, and injectors that I haven't fixed yet. For your high boost problem check and make sure your wastegate actuator isn't hanging up, mine was and was causing high boost spikes. One thing I tried to narrow things down was to disconnect the wastegate actuator, and the car ran fine with no boost, it had no power, but there was no hesitation. To me this means that boost leaks are the problem, not ignition, ECU or something like that. Good luck. I'll keep you posted.

Hey, I am having this same problem. Did you guys figure out what is wrong? I did a pressure test and found that I have a leaking injector and my 1g bov starts leaking around 14.... No matter where I set the boost controller (screwed all the way out) it still boost up to 17-18psi and makes a noise outta the exhaust then it slowly drops back down to 15.... Just now I found a exhaust leak where the downpipe connects to the O2 housing... Have to get a new gasket.

How is your boost controller set up and hooked up? what MBC do you have?
