I have a built ls/vtec and recently after taking out my vafc and rewiring my ecu i get a CEL after WOT in second/third gear

I can turn the car off and crank it back up and it goes away and is fine when i drive normal, the car runs good and pulls hard with no breaking up or smoking

I know my tps is going bad but when i had the vafc hooked up i never got the CEL, only after i took out the vafc is when i started getting it.

I was thinking the ecu is just getting overloaded and going into limp mode but im not too sure, the tune held and havent had problems with it, dosent run lean or anything

Anyone else run into this kinda problem with a chipped p72?
