The MAF is stock, the FP is correct for a LS1 car. Fords are rated much lower. Cleaned the MAF, the O2s are err 2-3 months old, as far as I can tell there is no vac leaks ( did the carb cleaner test)

Possiblities.. Cats clogged.. Im saying no, mostly cause when the car is seeing fuel through it, the fugger pulls quite nicely. Just seems to be part throttle like when you are gently trying to pass someone it just flutters, falls flat on it's face then slowly picks back up when the O2's see burnt fuel..

Other possiblity is that the O2's are just junk out of the box and should try some NTK's

Next one is that around where the EGR tube you can hear what is a vac leak (wasted a bit of the carb cleaner in that aera) could be that the EGR valve is stuck open.. But that would mean that it would run like crap all the time tho..

Time for a beer.
