I have a 2002 WS6 with a stock LS1 motor w/6 speed. It runs good as it is. I am about to install a set of 1-7/8 Texas Speed & Performance headers with their off road Y pipe.(no cats) deleting seconary o2 sensors.
Magna Flow Cat back. 3" (all the way back)
Stock lid with K&N lid filter.
Stock TB & MAF w/screen taken out
Stock injectors.
smooth bellows from Home Depot Pumping
Ram air hood (all baffles are ripped out)
160 degree tstat
3.73 gears (12 Bolt)
Everything else stock for now.
I have HPtuner Pro & I am very new to it. I have changed the Gearing & tire size. That was pretty easy.
I been watching Greg Banish dvd. I understand the maps somewhat.
I am removing the Cats. I don’t understand how to delete the 2nd O2 sensors. Could somebody email mail a tune that i can start with?
It looks like i need to get a wide band o2 sensor for my tuner.
I understand the wide wand O2 sensor is more accurate, but I still don't understand how the narrow band o2 sensors can run in your car everyday, but you can't tune with these sensor readings?
Does anybody have a car with similar mods? Just to get me started?
