I just read an e-mail showing a Ease chart on an 02 Z. The intake was the Halltech not sure which one. The LTFT were 14% to 20% LEAN!!! This confirms my suspicion that the Balckwing is not the only piece causing problems with an 02.

I am posting this for info and not looking for a pissing match.;)

Yea, I really think I am going to rip my Blackwing off and go back to stock. With a MAFT they work awesome I bet. I am not going to install a MAFT to much warranty hassles. I sure would like to see some AutoTap numbers without MAFT and one with MAFT.

I have not been keeping up much with this issue, and I'm sure its been covered in previous threads, but why does an intake cause it to run that lean?

Is the aftermarket intake that much more free flowing? I take it the Z06 does not have the ability to compensate for this (relearn correct A/F), or can it even compenstate. In WOT mode, is it a fixed fuel map, or can it use the MAF sensor to compesate.
