Loss in acceleration + throttle response ??

hmmm... those of you experiencing this sluggishness.... your AC wouldnt happen to be on would it? just a thought.

I have the intakes and my car takes off like a champ. However, when the AC is on, the car shits its pants.

AC on or off doesn't seem to make much of a difference. The car is just as sluggish down low with AC off as it is with AC on.

I've definitely noticed a difference like what was described with the AC on. It like wants to go but then falls on its face kind of like if the TC was kicking in.

Yep, same here.

It's even caused me to mis-time my shift into 2nd because it fell on it's face so bad from an attempted hard acceleration at a stoplight.

What's worse was, I was even under an over-pass, so my over-revving of the engine because of the missed gear got everyone's attention, all the way out to the gas stations on the corner! Yay! Look at me!







Now, if I wanna launch hard in my Z from a stoplight => AC and VDC are turned off.
