Just trying to find out what settings would most likely work best with a stock truck for WOT. Looking at the fuel and the spark right now, the shifts I've got work great!
Let me know guys. Thanks.

 

well.you need to go by your fuel trims.they need to be negative or at 1.56% max at criusing speed.if this is good then the predator tune should work.i am shifting at 5750 now 1-2 and 5700 2-3.i had my spark set at +5%.

 

Thanks for the feedback, I'll have to try the diognostic mode asap.
