Your truck should already have an improved "drive-by-wire" due to the installed Hypertech tuner. At $329.00 for the Sprint Booster, I think it would be wiser to purchase a SCT X3 tuner with custom tunes for the additional engine/transmission upgrades. Also, there isn't a version of the Sprint Booster for the Super Duty trucks.

That is pretty steep just to take out the throttle delay.
Even if you have a 5.4, check out the V10 forum's sponsor Mike at 5-star, he does custom tunes with the SCT tuners, and the combination of shift pattern, engine performance, AND throttle changes are well worth the extra $100 or whatever it is.
