I agree an oil will help but it's not nearly that much. I know because I've tested it. It was a peak hp gain of 1.5 rwhp. No hp gain within the curve though. That's even more hard to believe. Mustang Dynos read lower than a Dynojet. I'm thinking something was off with the dyno or something. Realize that I'm not calling you a liar. I don't want to start a pissing match, it's just really hard to believe. Something was off or something.
