so you made 241/266 with just intake, headers, and exhaust?

He did that with intake, headers, exhaust, and the URD MAF Cal. He went from one tune to a better tune (plus the t-stat and timing gears).

seems like reving to 6200rpm doesnt really do any good, if im not mistaken you reach max power around 5800rpm than it drops off......

Not so much for a dyno pull. But when your racing it makes a big difference. Think about what your rpms drop to when you shift. The higher rev limiter will keep you in the power band much better.
