Does is just lag after 6000 RPMs? Or will it not rev past like 6500 or so?

If the latter described is happening, it may be a vacuum leak.
A friend's MR2 did that, I could rev it to 6500 then it would refuse to rev past that, after fixing the vacuum line, it would rev happily to 7500 with no sweat.

Are you getting full throttle? Check the linkage.
