Mine pulls hard all the way. I upshift for dragracing at about 6700 indicated (1-2), then about 7000 for the rest of em...

Keep from smacking the rev limiter that way.

I know the actual RPM is higher than indicated and revs faster, especially in the lower gears. Mine has a LW flywheel though, so you may shift at a little higher revs. Never seemed the power was falling off at any point...

 

My car pulls really hard the last 1000 rpms or so before red line. In fact it sounds like it's opening up like an afterburner and just screams to redline. I do have the X51 factory installed so that could have something to do with it.
