Well i have had my typhoon for about 10 months now and i must say i am getting kind of discouraged. I cant figure this thing out.. and every time i think i have something fixed i scan it and its crap.

The thing i cannot figure out right now is why my truck would read 17.4 psi of boost on a stock MAP (says GM on it) and my computer has the factory seal on it. I was under the impression that the stock MAP/Computer would not go beyond 14.7 (ish). I am reading between 6 and 12 degrees of knock (even at low boost) and nothing seems to really change it. What is the highest people have seen with a stock MAP? Is mine malfunctioning? IM SO CONFUSED!

I would add a scan if i could figure out how to add attachments...

thanks in advance for any help/advice.

My ECM had the factory sticker on it as well (still sealed), but it had the Kenne Bell (Ka-Boom) chip installed. I'd take the top off the ECM just to double check.

Just a heads up GM does make a 3 bar map sensor so that may be why it reads that high and still says GM on it

Re: Noob here... Please help

Sorry i guess i never filled that part out. I am located in Cedar Lake, IN. I have spent HOURS on the link you guys posted. I have already replaced the plugs, wires, cap, rotor, coil, vacuum lines, i have a walbro pump on the way. I tried to email a scan but im using the demo still and i cant do anything with my scans for some reason. I will keep trying... i will go pull the computer back out and see if there is an aftermarket chip in it... will the map say if its 3 bar (although it probably is)

I havent replaced the turbo vacuum lines yet so that is my next step toward fixing the overboosting.

EDIT: The chip is definently stock. BBZA 1576. so.. how could i read 17.4 psi? map sensor reading incorrect?
