weird lsj problem? Any help welcomed!

well i got a 06 ss sc. all stock. but got some things going on with it. 2 weeks ago the car ran fine. and was great. then parked till today. Today i went to drive it around a little. Well im only pushing 4 lbs of boost acording to the gauge. And im barly cherping the tires in 1st gear! its slow, really slow! But the motor is running like a charm, no smoke, no werid motor sweeks or noices. Like i said last 2 weeks it was running great!, 10-12 lbs of boost, ran great. I have noticed one thing though. when i rev it up, and when i hang around the rev limiter (stock at 6,500 rpms) for about 1/2 a sec to 1 1/2, then it'll die? then starts up just fine right after (all revs are done once the car is warmed up, no civic owner here LOL ) ? i did have a check engine light, but i cleared it with taking the battery cable off, cause i cleaned my maf senor today. So what could be the problem? Im dumbfounded. The car runs fine, drives fine, mine doesnt even jump in the rpms like most lsj's cause i cleaned the TB. , but is boosting really low, and is super slow. I hope its a simple fix. cause this weekend i wanna put my header and downpipe on . lol but any help would be great!

i had it for a long time know, and my uncle went to check it out and it read the maf sensor. so its finally sunny in washington, so i decided to clean it, and unhook the battery, then hooked everything back up. and went for a drive and it did the same thing.

bottom of the supercharger, its like a throttle body that closes as the actually throttle body opens. and you know what thats actually a good idea, insylem i hadn't thought that far. because really boost can be dictacted on whether that is opened or closed. when its open your in vacuum, closed ur in boost (air only moving through s/c rotors instead of through bypass)

Even if the TB is bad, it should still be able to hit the rev limit with no boost.

Take it off an check the movement for it, it may not be working correctly. If you need to get a replacement call ZZP they can get you a new one. Call, and leave them a meassage and leave your number they will call you back. Def sounds like the actuator isn't working properly..

Have you looked at all of your vacuum lines? I would check those before replacing the bypass. It's possible you have a leak. That or a s,all rodent creeped into your intake and is reducing your airflow pre-maf
