Hey Guys,
I just got EFI Live installed and going and I plan on tuning my 2004.5 LLY. I had super chips and the truck was in TOW mode forever. I was curious to see the differences between the stock tune and superchips tune. I compared them in EFI Live and became quickly confused about why it makes more power. The super chips tune has the same numbers in the desired boost levels with EGR off table (truck has EGR blocked). It only has slightly more fuel added to the throttle base injection table. It only has a small bit of timing added, yet it adds so much power.
My question is should I mess with my timing or just with TBIQ? Will increasing my fuel a lot but leaving everything stock damage anything?
