:notgood:Well I'm Back. My car will not rev above 3000rpms.It will surges and backfires going down the road. I can smell raw gas and see black smoke. 1,2,4 plugs black and shooty 3 is kind of white .My has car has all the vacum removed and EGR blocked off. My MBC is only set to 8lbs. Could a fault Fuel reg be to blame. Its the stocker.

Well you're obviously running pig rich.

Why? That's another good question. I don't see a bad o2 causing an issue of THAT magnitude, and unless you've got mods not listed in your profile, I don't see a REASON for it to be that rich.

It's always unwise to turn up the boost without having the correct equipment to properly tune with (ie. wideband or logger). Maybe your issues lies in there.

I'd do a thorough BLT and go from there.
 
I forgot to install my new pvc and buy a check valve..<-- My Boost leak. Thanks guys... I really feel dumb. :)
