Well, yeah! In theory and concept, that TOTALLY makes sense... but it really seems as though I am able to reach a higher speed in each gear before hitting 4,000 rpms... I'm talking about accelerating through all the gears, and not coasting... what you said, rabbit, about the engine having to work more before the intake to get there (90 mph) explains it... I think that's what I am noticing, and I like it a lot!
