Throttle Response
Truck works great, drove it out of the garage yesterday and the first thing I noticed was the throttle response
. Very touchy. and a whole lot of power in 1st gear. Is there different throttle peddles, TAC or what ever makes if feel different than N A carb, I know There is a difference in FI but, WOW what a difference , can you say wheel spin!! There is new 275 tires on the back and they seem very "slippery"

Re: Throttle Response
DBC or DBW? You're tuner should be able to help you out with this.

Re: Throttle Response
There is a section for DBW control in the tune called Pedal Droop or Droop/Fade, which controls how much input yields how much output.
It can be very useful if you have a heavy stall or are running something like a turbo, where the droop can be used to make the pedal travel more functional. No reason to have 20%movement at only a tip-in, and the same goes if WOT feels too "early" in the sweep.

Re: Throttle Response
Thanks guys, it is a DBW, forgot to mention
Great to know that it is controllable, but only by the tuner!
