Go buy a gallon of denatured and try it out with your race chip. I promise with the results you get you won't go back. You can find denatured for fairly cheap if you look around and get it commercially. You also won't have to have your pump speed set really high. I have mine set at 8 and thats enough for 23-24# boost with 93 octane and race chip. Keep in mind I only have a stock IC and live in Texas. Those with a good IC could prolly run more boost. I should be getting my CAS V4 next week, can't wait to see how it works with the alky!
