yeah vegasdsmr is right. Our cars are tuned to make power at certain rpms. I believe for stock our power gear is 3rd so you'd redline that. The rest of the gears you power tops off at 6.5 so if you go past 6.5 you won't feel it pull as must so you should just shift. I guess it depends on mods also, not too sure myself on that. Hehe but if you have hella highcompression your power is up top I know that.
