Yeah, my 5AT is slow alright . . . just murdered a few high-powered cars at autocross this weekend -- a couple of Z06s, a Ford Cobra, a Porsche, and a several STis.
Unfortunately, there are still a few drivers who compete at the National level (one former National champion several times) who are still faster than me.
With the right mods, your 5AT can be real fast . . . here are our results (fastest raw time of each driver) from yesterday's autocross (I'm #18):

The 1st three are shifter carts so they don't really count. #4 is one of the fastest driver in the country.

BTW, I'll be talking to you about your FI Z. You have the Vortech SC, correct?

No tranny cooler. Most of the runs in auto-x are between 40-60 seconds, mostly in 2nd gear. Really not too hard on the motor & transmission, especially if you have good lines & you're smooth. But after yesterday's launch at the start line at around 4K RPM & redlining 1st soon after, I may need one . . .

Launching at 4K...are you sure about that. Theres no way you can keep the tires from breaking loose with your foot on the brake at 4K

MT or AT its all similar performance. i just think AT kinda kills the feel the Z gives. downshifts are just boring... heeltoe is the way to go!
Either way the Z is the nicest and Best car for the $

I don't think it does a fuel cut... the throttle is electronically controlled so I see no reason the computer cant just keep the RPMs below 3000 if you have the brake applied. I read somewhere that you could disconnect something under the rearend of the car, but it was never specified what. Maybe disconnecting the brake position sensor (is there even such a thing) from the ECU? So the computer doesnt know you have the brake applied...
