Bimmerteck, the NOS guys have always been great for me too when I had questions. I should have added that I installed my system which did save a ton of money.
Originally I had a one injector setup, but then it became a 2 inj setup, then added the progressive controller, then the M5 LSD to get all the power to the ground.....it just kept snowballing to what I now have. This is it, I want it to stay together.
I got the idea from a Gene Fulton article I saw in Hot Rod magazine a few years ago, he had 5 stages of juice and a much bigger motor. I spoke with him to get a few pointers.
If your into "over the top" power it's an interesting article.
