It is a tuner # 2815 flashpaq Ser # 1477689
I live in Wash State.
My trailer was loaded to around 4500 lbs.
My engine vin is a 3..
The truck has NO other mods..
I always run 92 octane in the truck. I haven't tuned it to the 87 octane tune yet. Do you think I would have any problems leaving it in the 87tune and running 92 octane and towing?
No, running 92 on the 87 tune would be fine for towing that weight.
