Trying to get a handle on this truck, ive been messing with tune and I was hearing a pinging noise during an uphill drive at constant speed. Not sure if its low octane related I run 87 in my truck. Attached is my Log and Tune File, truck has CAI, catback and transmission thermostat delete.
Knock I was searching for begins at 4:00.000.
Any tips or tricks would be helpful!
Thanks
