What chip do you think is best for performance??
You could always try a shift kit or the resistor mod but that will not change your shift points or rev limit so I don't know if that is what you are looking for. The other option which some guys have done is stack two tuners on top of each other. A SC for the shifting and then a custom tune from SCT or DS.
But i can stack to chips tho if i needed to so thats good to know
