Ok so i have been through a lot of problems with the SR , it seems like my problem is a boost leak but it only boggs and misses when your "cruisin" or light throttle. I can punch it and it smokes ALOT but it hauls ass.... it is constantly smoking even at Idle, black and white. Someone mentioned maby to much fuel pressure but its a tuned ECU and havent had a problem yet, not saying its not that but still. Also the Idle is all over the place, 400-1800 and it sounds like a damn V8. Any help would be appreciated.

Start, with a compression test.

Then get a mechanic to test for co2/fuel/exhaust in the Coolant.

If you pass this test.

What is your vacuum at idle? You probably need someone to do a full SR "set up sequence".

it varies from -99 ( good ) to low -70's and high 60's on my profec B II. I was hoping to sell my car before it blew up so i hope shes not a goner yet :)

Its the white smoke that bothers me. Usually white means coolant burning through the chamber.

But like you eluded to, it may be either the AFM (wiring, pipe..) or a bad boost leak.

I love the overcomplication of life...

lets start with something very simple

whats your fuel pressure?

1. at idle with vaccum hooked up
2. under load and boost (when its puking).

what fuel pump you go?

check this crap out and pm meh or just reply back maybe someone else can help you with a simple answer.
