I have a '99 Boxster Tiptronic that I AX and one of the issues I have with the trans is it will not downshift under most hard braking and turning maneuvers leaving me coming out of the hole in second gear, which is where I generally end up running most AX's in. By the time I've built up enough speed to reach the RPM required for maximum torque and HP it's time to brake and turn again. The power band in second gear, where I am usually, seems a long stretch even on strait-aways. My question is is there a way to bring the maximum torque and HP on at a lower RPM than 6K, say 4500 RPM? I'm not looking to increase HP just have what is there available sooner.

A supercharger will do both, especialy the low-end torque. A n engine swap will do it to. But I don't think thats where your going. Short of that, you'd need somthing to boost hp and torque all around, that's no small trick with the box. No quick bolt on that I know of has really shown to do that and no way to do it just at 6000 in 2nd only, as a "doable" compromise.

The box is pretty buttoned down from the factory. No easy wat to milk any more out of it.

Suggestion: Just keep the rpm between 4k-6k when AXing and drive the car. There are a lot of drivers in SoCal who AX very well with Box Tips. Most just leave it in 2nd and focus on the line and getting their corner entry speeds right. I think max torque is 4800 in our cars so you can use all of it.
