If you want a fuel controller and you don't have any immediate plans to get into the engine (cam, piston, ect.) I have a dynatek 4 dial I'll sell you for a 100, plus shipping. I bought it used about three years ago and ran it with a open airbox with K/N and CT Racing full single exhaust. I haven't bothered to list it, it worked very well for me when running a big 3 setup.
If your getting in the motor soon I'd save your money.
