Default About how much to scale the IFR table with TR230? Please???

We're trying everything we can to get my friend IFR's even in the ballpark, and we're stuck until we find out where the problem may lie. It's an '01 Z06 by the way. We had to pull the intake during the cam swap because a lifter fell, and we're 99.9% there is no intake leak, but we cannot get the LTFT's in check. They go to a low of about 11 in cell 6 and a high of 25 in 19. We've tried to scale the IFR like everybody says but the car is PIG rich at idle, and probably everywhere else, but we can't smell it while cruising. The 02's read around 950 at WOT, which I know is rich, but the LTFT's lock in at around 10 at WOT.

When we scale the IFR down by 4% (multiply by 96%) it helps the LTFT's, but performance suffers bad and it burns your eyes at idle. We just want to make sure that we are in teh ballpark on what to scale the IFR to before we go tearing into the car looking for intake or exhaust leaks. Thanks for any help you can offer.

I didn't have crazy Lterms like that after my TR230. Did you double check to make sure it all went back together right? Wiring is all correct?

What all is done to the car, we need more info to get you a better response.
