Stock motor, 3" exhaust with a resonator and cat inline. If anyone sees anything that looks out of line, please voice your opinions!
Actually 15:1 is optimal where the most efficient combustion takes place. However that is so hot it melts the internals as we all know. So 11.8 is getting close to the danger zone (12.5 if I am correct), it is nice to see a safe buffer between that. You won't loose to much HP/TQ if you do that, and will ensure a safe motor.It's holding at about 11.8 with a slight bump to 12 for a 200 rpm range. I thought 11.8 was optimal, does this no longer hold true?
