it acts just like it does when u blown an ic pipe off but it idles and drives just fine and its all the stock turbo stuff. mods: bc 264's,3"exhaust, arp head studs, titan motorsports head gasket. ok problem is ill be driving as soon as it start to hit the zero on the stock boost gauge it will act like there's no power and if it hit all the way down it will have a very repetitive exhaust note for second and bog. my bov i think is messing up and letting air out or something because all the pipes are fine. my afr is showing it is really rich while bogging. also my bov sounded like it was like whining when it blew off earlier p.s. still running 7psi

yes stock afm and one time it did it i got code 52 and i just reset it i know that code is a common problem do to old wiring but i know it isn't running lean and i run only premium gas and it has only done this to me twice with out ic pipes being off that's how i knew it felt like that. and i said stock turbo so its ct 26. i have two afm's i could try the other one out. i just got done replacing all the vacuum lines and stuff but the bow is real old and its like a Chinese one.

Code 52 is knock sensors which will not let you go fast anywhere. ID check your codes again and see if its back. Clearing the codes is not going to solve problems.

Bad wiring or a bad sensor.

Arre you sure you dont have a boost leak? Fc generally when you hit it its like hitting a wall. and then it will throw code 34.

ok its throwing 34 and 52 :( i think its the bov because earlier it was making a screaming sound and it wasn't blowing off properly it was acting weird and some times it would act right

52 plays a major role. Of course you can still drive the car fast but once you try to put your foot down the peddle your car is going no where. It's retards the ignition timing and runs rich like heck once that code pops up.

90% of the time it's the wiring. I just re-wired mine a few months ago and I can boost once again (YAY!!)
otherwise it's just like any other daily driver.
