Been gone for a while but, glad to be back. I have searched this and have gathered some info but, was wondering if any of you have discovered any new data? My 3.9 pings at low rpm when I am just cruising let's say in drive and give light throttle I can hear it. I also have noticed a seperate issue, when it's hot out (100+ here in Nor Cal) car seems to be very lack luster in the performance dept. I don't have a CAI just stock box. Any help is greatly appreciated. TIA.
