Power Delay with engine 
WHenever i drive my 98 trans am A4 i always have a delay. i slam the gas and thier is a slight hesitation and then i feel the power kick in. i notice this at any speed and its only when the TB is open to a decent amount. Has onlyone noticed this problem? What could be a possible sollution

mines doing the same thing....so far, i've been doing some research and it seems like the tranny is delaying the downshifts, making the car feel kinda flat.....try to get it on a scanner and see whats going on with your tranny functions.
There is a finite lag between transient throttle and
TCC unlock, and another between this and shift
kickdown. If it's a hard power jump this may be your
pony. If it's more like groggily deciding to make output,
this could be some high closed loop error that is being
comp'd out by the LTFTs, but exposed on every change
and needing to be recovered.

who are u referring to??? me or Andrew1?
if its me, then its not the torque management because this is a recent thing...when i said delayed shift i mean REALLY delayed...
also from what i remember, 98s never really have TM issues after modding, and both his and my cars are 98s...
