Unless I use Premium gas the car will on occasion ping on light acceleration, after being driven for over 15 minutes. Does eveyone else have to run Premium gas? Currently I have been using Shell Premium. Would a 180 Thermostat help?
If your car doesn't ping on 91 or whatever your premium octane is.. just use it.. otherwise, if your car pings on that stuff, as my car did with the stock tune, a dyno tune is the next move.85MustGT said:
