w/ manually shifting it upwards you can utilize a bit more power when not driving at WOT (wide open throttle).
When it's at partial throttle and you shift it up at say 4k, you'll be making more power at that 4k than you would at say 2k when the computer shifts it.
Now say you're at the drag strip and you're at WOT and you run 1st gear to 6k then shift, then 2nd to 6k then shift.... there are times when the computer will not be ready to shift when you tell it to... so you may be at WOT and go from 2nd to 3rd and it'll keep climbing in revs until the computer wants to shift. This is not BAD for the car per say... but unfortunately it can hurt our power...
When you go to shift at say 6200rpm which is your peak power, but the car runs it up to say 6500rpm, that 6500rpm mark is usually going to be after your powerband starts to drop off...
As for Neutral Drops... those are TERRIBLE for the transmission.... What a N Drop is, is when you put the car in Neutral, run the revs up to say 5k and then dump the car into a drive gear at High RPM. this is almost an instant way to blow up the weak clutches that we have in our ATX tranny.
Hope this has helped
