help with turbo build I'm working on a turbo build for a 5.3l. Ill be using a 5.3l pcm i think its a 02-03 pcm anyways i have a couple questions. Can. The pcm i have be tuned to run without o2 sensors feeding it and with out a maf? I'd like to just run a wideband in the down pipe and have the pcm using the map sensor to control fueling. I spent sometime reading about this and i got more confused then when i started with people saying the os on the pcm needs to be changed to run speed density and what not can anyone clear this up for me
