Yea, I have an upgraded valvetrain, i just want to know if i should go 5,000 or 5200. I usually shift at about 8800 when racing, maybe 8700. But all I know is that in second gear at 6500, when I punch it, that beast flies. I Just want a few more HP's and if all i have to do is change a chip so be it. Anyone know any good upgrades to do, to improve my take off on a rollon in second gear? By the way I do have the Mugen ECU running.
