high end rpm gone

well I"m really hoping that this will be my last post of a problem plagued summer. My 2003 rr has lost all of its top end. As you accelerate from stopped or even slow speeds the bike operates fine, but as soon as you start to go and get into the higher rpm the bike begins preform poorly. At around 10,000 rpm is seems sluggish and hesitant then as you approach 12,000 rpm it is almost seems like a govener kicks in and it just wont let go. I'm at sea level and have had multiple gas changes of 91-94 octane gas. Recently i had my map sensor changed, and it wasn't until after that i really noticed this problem. Would this be a secondary injector issue?

I was waiting for you to tell me this had a PC3 !
It may have failed - remove the pc3 from the loop & test is what I'd try
- you HAVEN'T connected the PC3 to the upper injectors have you?

when i had first put it on i made the common mistake of hooking it up to the secondary injectors. But changed that as soon as i found out that it wasn't correct

Good to know !
Just take the PC3 out of the loop (you only have to temporary remove it)
Undo the tps & 4 injector connecter's & put the originals back on - take for a spin. If no difference, then its not the PC.

i'm not going to be able to get the time to take out the pc3 for a couple days but if it isn't the power commander how would a go about isolating the issue on whether its the computer or the injectors them selfs

thats not a bad idea to clean the injectors - get something that you add to the fuel & follow the instructions. It won't hurt anyway.
