Bru ce, I have a cheap 1:1 reg that is anodized purple, made by weapon-R. The only reason i didnt use it was because it has 1/8 npt fittings. Kinda small but it will work. send me a PM if you want to work out a deal. The Aeromotive Regs are preferred. There are 2 different ones you can use. the cheapest is 115.00 and either one you will need to buy the fittings separate

As for the injectors your best bet is to get a set of 450cc injectors off a stock Turbo DSM which should cost you no more than 80.00 if low mileage.

As for tuning the MS, dont spend too much time beating your head up over the manual. When you get it in front of you on your PC it will all come together. Besides pretty much all of us can help you through the minor details.
