3) Factory nissan power peek is at 7,000 rpm. Car should shift/be shifted 300 to 500 rpm ABOVE H.P. peek. Example 7300 to 7500 rpm. The reason for that is that after every shift, the rpm drops. You DON'T want it to drop too low! Keeping the peek h.p. in the middle produces best results! As a bonus, it also keeps the car from going into 5th.
4) I don't know all your mods, but if you have after market exhaust plus other mods, your H.P. peek is no longer at 7000 rpm. It could be 7300 to 7500 rpm range. Now you or your shop should correct/change the shifting into the 7500 to 7800 rpm range.

It is pretty good advice for most people that arent aware of how their powerband works. I've yet to take my car to the track since my tune, but I can tell you this, at 7600-7700 it was still making power on the dyno. So I will be shifting around 8k, at least for one run
