Tuning changes when running cats? I am putting on dual 3 inch carsound cats Friday morning. I wanted to get the tune touched up and was wondering what you guys typically see when you tune cars with cats?
Right now I am making 458RWHP/438RWTQ through the exhaust (~466RWHP through single cutout in intermediate pipe)
timing is 24 degrees, AF is at 12.3 for now. (Car seems to like 12.3:1 on 94 octane)
Any suggestions tuning wise? Anything I should look out for?

Do all Canadians flout the law and try to trash their environment? I'm sorry Chris, but all the other members of LS1Tech are law abiding citizens who wouldn't have had the cats off the car in the first place.
