With the stock tune I logged ZERO ST KR and ZERO LT KR.
I can load the DS modified Stock tune without actually modifying the tune and I get up to 7 ST KR and up to 4.5 LT KR. The problem is that I am looking at is that it happens at 60-70 MPH with the cruise control on or if I slow down as to turn a street corner and give it a little gas after completing the turn to it pings like crazy.
I have tried different gas thinking octane ratings are not what they should be. The fact that it happens with the stock modified tune, the 87 tune, the 91 tune and 93 tune all with 93 octane gas but not the original stock tune leads me to believe that there is an issue with baseline timing.
In my mind you should not hear pinging when giving it partial throttle from a stop or slow roll before giving it enough gas to down shift.
I don't plan on doing heads or anything of that nature. I may go to headers, TB, exhaust, and of course an intake. What tuning plan do you recommend?
