VS V6 Hesitating before reving in park

[VS_WPN]

I have a VS V6 Auto..car is modded (Heads,runners,exhaust,bigger TB, CAI..+more). When i first start the car [somtimes this will happen] whilst in Park when i go to rev the car it will hesitate then accelerate/rev. When i put it into drive the car will run normal.

sounds normal to me when cold. ... If not i got the same problem as you hahahaa.

if it only happens when cold, its normal,i work with brand new fresh of the ship and the do this. otherwise it could be a number of things likefuel pressure, timing problems etc. if your not competent take it to a mechanic
