I hear this statement all the time and I can almost guarantee that your engine has pinged more than a few times if you're running a Cobb base map.
Thanks

I'm running stage2 cali now. I'll reply if I see any noticable affect on performance.
Thanks
That, and the ECU automatically starts to retard timing if minor pinging is occuring
Looked at my AF curve...10.8 at idle, 13.1 at max power (5500rpm) , avg of 11.2

Also, you guys are right, I have no idea if my engine has been pinging or knocking. I've never done any fancy testing but I will say the car "feels like" it's running smoother with the Cali map applied. How's that for scientific analysis.
