Anybody know much about the ECU in vehicles? I've got an '85 Trans Am with a Chevy 350 engine and 700R transmission. It already has alot of power, that 350 screams in it. But I was wondering if there was anything I could do with the ECU to increase performance, econemy, or other variables of my engine?

My friend ryan has like 2005 chevy 1500 and he put this Vortec chip in it... it made his truck so fast lol.
