If it were me, Id buy a SCT tuned chip. Thats what Im going to do, because, to me, it will give you more for your money, and you can have the person do a lot more. You can also put it on the dyno to check as you are doing it. This is what im going to do, and I was planning on a predator at first, but decided against it. JMHO, take it for what its worth.
