Bare with me as ill do my best to explain this... Long story short...

When i start my car & it idles.. after a sec or two car comes out of vaccum & starts creating boost, i'm not applying gas or anything (when i do i becomes worse). It gets to 20psi or more, start stumbling real bad at 15psi & loses power as its not getting any fuel.. After 2 attempts in trying to get it started disconnected battery (negative only), checked vaccum lines etc.. no luck.. Also smell fuel from the car too..

Any ideas??

I'm trifecta tuned with hahn cai, cbe & mpx downpipe.. before this happen i did a 2nd gear pull & got some backfires. (1 as i was getting to redline, 2 as i left off and came to a stop)

 

Saw this on the css gang on facebook. Your thinking stuck wastegate? Everything look normal under the hood? any vac line disconnected?

 

Yea but friend shinned some light seems like its my map sensor

 

Idk how ur turbo could create so much boost at idle, waste gate shouldn't have anything to do with it since there isn't enough exhaust pressure to create boost. Maybe some issue with a sensor that is causing a timing issue. Cars use timing retard to create boost on anti lag systems. Think that's how it works, but ur car would be popping and backfiring. That's the weirdest thing. U sure its not just a sensor bad making gauge read wrong and causing the car to pour fuel in to accommodate the fake boost? that would cause ur car to choke as well. I'd say sensor. No way ur car can boost to 22 at idle. Physically impossible unless anti lag. And ud hear it spool. So bad sensor which is lying to ecu causing it to spray fuel is my guess

 

And that's why ud be smelling gas as well, cylinder is getting flooded

 

Yup. Bad TMAP.
