2009 Busa need advice

You will need the PC for an a/f map with an AlienHead.
You'll need an ecu flash to have the top limiter removed, along with a few other changes. That will remove the fuel 'soft cut', and ups the rpm limit by 600.
The fuel 'hard cut' remains and IS the rev limiter.
You still can't go faster than 197mph.
You'll need a -2 rear sprocket(41t), or a 55 series rear tire(taller), no mirrors on, and good conditions, then 202-203mph is possible.

The ecu can also be flashed with an a/f map for an AlienHead, eliminating the need for a PC.
Thank you so much
You're welcome
There are many threads on this subject....go to the search function and simply type "200 mph" and many threads will pop up...
Although they all will point towards the same advice @sixpack577 gave you, they still make for interesting reading.

So should I not purchase the PC and just find someone to flash the ECU for the A/f map?
Yeah it can be a bit confusing. I called a shop and they said they didn't have the software to flash ecu so I have to call around
The ideal scenario is to flash and dyno tune the bike to make sure the A/F is spot on....but even a good flash by a well known tuner can get you real close..
Can you courier it to Moore Mafia or one of the other re-known tuners?
Even a few on this site can flash the ECU for you...
That will take care of the software then you will need to take care of the hardware when it comes to gearing, lowering, etc....
There are many here who are versed on LSR and can assist you in proper riding techniques and how to tuck properly...
As @Bumblebee stated
Contact Moore Mafia in South Carolina for an ecu flash with an air/fuel map on it also.
That way you don't need the Power Commander.
Ok I will look them up. So if I have them flash my ecu for my new brocks exhaust do I still need someone to tune it on a dyno?
No, the base map they'll load on there will be sufficient.
It's just an a/f map from another dyno'd gen2 with an Alienhead, and it'll work fine.
Maaan you guys helped me so much. Also......where is the ECU located lol?
Good, I'm glad we could.
The ecu is under the driver seat.
Disconnect the battery before unplugging the ecu.

good idea to find someone who knows the flash-program well.
the PC is one more electronical piece that can cause issues.
