Another new guy here. I have a stock 03 5.3 with 4L60E in a 83 El Camino. No significant changes to the tune other than tires, speedometer, injector flow table. It's been running rich and throwing a check engine light. I need to adjust the LT fuel tables and how do I set the MAF sensor to fail?
I've been reading up on some general instructions for tuning http://www.ls1.com/forums/f9/tuning-...ptuners-46733/ and one of the first things is disabling the MAF sensor. This guide is based on a previous version of HPTuners and I can't find where to turn it off on the current version.
