ok so i had my car dynoed and the guy said my AFR was way to rich so i began to look into the problem looked at the dyno sheet and did some datalogging. I then bought a wideband o2 sensor and guage and sure enough it runs perfect at everything except WOT. its at about 14.7 under normal load and cruising, but once i go WOT it goes down to 10.2, and i would like to get it up to 12.8

i have a 5.7 355, 700r4, TPI speed density, 7730 ecm, using aujp.bin and the 8D.xdf

i have been using tunerpro rt, can someone help me figure out which table to adjust on tuner pro to lean it out at WOT? and how much i should change the values.

your help is much appreciated!

thanks

 

You need to adjust the (P.E. % change to fuel/air ratio Vs. RPM table) smaller numbers will add less fuel.
