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?
