Review on Innovative Performance Chip Power Programmer Replacement Parts by Drexel Wortham

I bought it a while ago and didn't install it because the instructions weren't clear and it didn't fit my e46 330xim54 engine specifically. It also requires cable splicing, which is a big minus in my opinion. Should have come with seat belts. Also, since I've plugged it in, it's hard to believe it actually does anything.
