Default KR at high speeds 110+

I think the car is either loaded too much, or is running lean at these speeds. I am leaning towards to lean, because it only happens at very high speeds.

I shift into 4th at about 112 mph dropping the car from 6800 to 5300 rpm. At this point, the KR always peaks at around 4 deg and slowly decreases to 1 deg around 6000 rpm. There is no KR in gears 1-3, nor at lower speeds.

I need a table that adjusts the fuel added for changes in intake pressure. Is the FUEL AIR MULTIPLIER table the one that I am looking for?

I don't want to adjust any fuel / rpm, because the a/f is good throughout the rpm band in the other gears.

Anybody else have this problem? Has anybody made adjustments using the FUEL AIR MULTIPLIER table.

Thanks

I think I just found the problem.

Injector duty cycle ---> 103% <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
