I have tuned my VE tables on my 94 K1500 and have gotten them pretty close, all within 122-130 (though a couple of cells seem to have strayed a little on this run). Anyhow, I've re-enabled PE, hooked up my WB02 and made a new datalog and started researching how to adjust PE. I'm a little confused...with the PE AFR vs RPM table set to a predetermined AFR (12.1 - 12.6) , why would my truck be running as rich as it does under WOT (as rich as 10.3)? Do I just go back into the VE table and adjust it to bring PE where I want it? Also, I read varying opinions on PE AFR and what it should be adjusted to. Is this more of a preference or feel for what the engine likes? Last, the TPS for PE vs RPM tables are still stock vortec settings, would you guys leave these alone? Any help or opinions to get me going in the right direction is appreciated. Thanks.
