ok so im back an i have it all figured out. i finally lifted the car an hit my cat an it was rattling like a car of marbles. got it fix took it out an BAM 11psi scared the living piss out of me. lol but thanks everyone for all the help an ideas thats why i love this site

Exhaust... I knew it! Glad its all fixed man

Well that will do it.

Wait...you have a bridgeported car, running a stock ECU, and a cat?! Why?!

cause when i first built the car it was a streetport very very long story aaron. but its not just a stock ecu its piggybacked off a hks fcon so i do have some sort of fuel computer on the car. im almost done loading my settings to my ms1 so its not going to be like that for long. an my idle is at 13.2 an boost is high tens so im not much worried about it leaning out an blowing up.

also i have a cat cause i live in colorado were i have emissions an had to pass.. THen never took the cat off...but i have it under control dont worrie

Tuning bridgeport fuel requirements is easy. But they require a much different timing curve then the stock ECU can provide. That's where you need a standalone.

You will never pass emissions with a bridgeport, and the porting will clog that cat in very short order.
