Extension Box's On A 388?
Is anyone running stelling ext boxes on their slingshot? I have a 99 Slingshot with 500 EFI that I am interested in getting a little more speed out of without upgrading power. If anyone is running the boxes what lower units are you using? Currently just have Bravo I's on mine.

I think im running in the 81-86 range depending on weather conditions! Notice a big difference in the rpm with a little cooler weather. I'm weighing all the options, complete repower, upgrading the 500efi's (which apparently is tough to significantly improve on according to most threads ive read), or possibly even whipple them. But i thought i would start with smaller stuff like boxes to get everything there is to get with the stock power. Just cant seem to find anyone who has played with this setup on a Slingshot.
