Part of what I miss is a cable from my foot to the barrels. No matter what tune there is always some throttle lag and computer input, it better but not gone.

 

I REALLY wish I'd have gotten a slightly used GT500 instead of my new GT which I supercharged.

With a simple CAI & tune, you can add 80hp as will as massively improve the silly factory throttle response.

The next step...CAI, tune, pulley change, spark plug change, and recommended intercooler swapout (for a larger one) - adds 150 hp easy. Just like that and you've got a very save well over 550rwhp. And that's all I'd do to one.

A friend has one. He put a KB blower on it and makes 700rwhp. Safely. Allegedly. See...I'd be happy with 550rwhp. He can't drive he car hard without smoking the tires, even with drag radials.
