Got a 3lb lower, denso plugs, and a dual program chip. On the performance side I've noticed a little pinging, usually when it is cold out. (about freezing) I had a pinging problem before I installed the lower when I had the chip in. When I sent the chip back for a reburn, they made note of this. I believe I am just getting poor quality gas. The question is, when I run the performance side, can I run VP race fuel in it, and how much would be recomended. I can get VP race gas and Cam II easily and cheaper than bottles of 104 octane boost which is why I would rather run the race gas. Any input is greatly appreciated. Thanks
