2010 for me. I agree with bpdutton, throttle response is much improved with a tune. Prior to the tune, if I was going to merge into traffic from a stop I would hit the tow/haul button, otherwise the truck had a delayed response and then eventually would jump to 4k rpm. It was difficult to hit the middle ground for acceleration, at least it felt that way to me coming from my old 4-speed 5.4L triton.What year Avi’s are you guys driving?
I’m completely new to the whole tuner game, so I’ve got some reading up to do.
