I have a 93 r1 with a high flow fuel pump. I also have an Apexi Power FC . How would I change the cars boost with out messing up the car.

 

FLOMAN,

Send the P-FC to XS engineering in fullerton, ca and they will reprogram it for you. It's only $150 . You can modify the fuel map to tolerate higher boost levels but it's very very likely you will blow your motor before you get it right. Trust me on that one. Everyone thinks they are smart enough to figure it out but...........
The $150 is a small price to pay. You can increase the boost but without more fuel you'll be talking to pineapple racing about a new motor.

 

Uhhh...

The PFC already has the maps for up to 17psi.

You should be able to run at least 12 psi with the stock fuel system, base maps, and normal mods. What do you have other than the fuel pump?
