Can anyone clue me in as to what could be causing this problem. I have a car thats air/fuel goes well into the 10to1 range under wide open throttle. No matter how much fuel I take out of the PEvsRPM table there is no change. It seems as if the computor is not switching to this table under wide open throttle as it should, but relaying on another table for fuel control. I can take out 40% fuel & the air/fuel stays the same under WOT. Any help would be much appreciated. I thought of disabling the COT but the car still has cats & I fell this might just be a band aid to the problem.

What does your Injector Flow Rate Table look like.
What frequency is your MAF reporting at WOT.
What is your setup?
Stock fuel system?
Odds are the range on the wideband that you are using is 10:1 to 18:1. So more than likely, you are waaaay richer than 10:1, so much so that the PE vs RPM table cannot compensate enough.

It is a supercharged (8psi) 02 Trans Am with 42lb. injectors, inline helper pump & FLP long tube headers. The Injector offset has been changed for the larger injectors. I will have to check my mass air flow at wot. <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />
