See link to thread I posted above. Last time I checked 40% 91 octane users have pinging.I agree how did you know you had ping and did you fill with minimum 91 octane? I waited until I was almost empty before filling my tank with 93 octane then I made the appt to have power pack 2 installed... The best benefit of the tune is the no lift shift...
