Hmm. Well, those of you have this issue (especially those who have aftermarket intakes and no tune), definitely see about spending a little time on the road playing with tip-in fueling.

Best way to do this is big open parking lot (stop and go with various degrees of throttle input) and then empty road to play with this at crusing speeds.

PITA to tune, and pretty much all done by feel (i.e., there is no target AFR per se, it's just what feels good -- typically this involves skewing a tad rich momentarily, although ideally it would go directly to whatever AFR you would have in next map cell).

You should also be able to tweak tip-in ignition too, which will make a huge difference in responsiveness. Torque output restrictions on tip-in generally involve pull timing.

Put it back (with a slight risk of burst knock, so be careful!)and you will get way better responsiveness!
