Thats WAY too high for your setup. Our springs will start to bind after 6700 RPM and if you are comanding it to shift at 6500 then its really not shifting till almost 7000RPM because of the gears and just the fact the trans dont shift that quickly.Who knows. I have mine set at 6500 rpms in 1st and 2nd and they are too high. I was reading another thread that got onto the topic of shift points. Opinions vary, but in MY opinion from what I have learned, if the powerband dies off at 6000 rpms, there is no sense in wasting time winding it out to 6500 or 7000 rpms because you aren't making any more power doing that going into the next gear. And for what it's worth, I too have the Cobra intake. I think it does make more power at higher rpms than the stock intake, so all I can tell you is that you will benefit from higher than stock shift points. In my case, 6500 is a bit much and they will be getting knocked down. It might be hard to part with the awesomeness of higher rpm shift points and the car being seemingly faster, but don't be fooled. Your car may be faster with lower shift points.
With your gears if you want it to shift at 6500 then you should command it to start the shift at 6000-6100 RPM.
