Well, the first I did was a Needswings intake. It actually makes some power and allows the supercharger to be heard. I just installed a Code 3 supercharger pulley. I choose it over the others for the ease of instal and ease of going back to stock. It had a few quality control issues, but it works good. It seems (no dyno proof) to really boost power in the midrange. I can't say I feel much difference at redline ... but that's mostly because I loose traction so badly that the car is shifting early. I've read the Code 3 won't show much increase in peak power. I can't tell you about a tune, still don't have one.
