Suggest you go and read some of the info about power adders on the Dept. of Boost website. Good read. If I remember right it pretty much says boost is boost. Of course, extreme requirements for space, ultimate power, etc can make that a bit misleading but if you're just looking for fun on the street then a good, easy to install, intercooled kit is probably your best bet. There are quite a few TVS based kits out there and of course Whipple (what I have) works too.
Black Friday sales might just make one a whole lot easier to love than another. Read up and you can be ready to pull the trigger.
