Hey my motor runs kinda crappy at idle missing and stuff but when you give it gas it clears up and revs great after 3000rpms...? i installed this rc 51 motor in my polaris rzr... is there anyway you can delete the front BARO sensor thats in the front nose intake of the bike??

You can remove the baro sensor, but it will always throw a FI fault code and the FI system will not be able to detect air density and default to the standard altitude of 29.92 In. Hg. It may also not run as well as it could.
For most of the non-critical sensors, if one goes bad the system goes into limp home mode using set default values. It might not run well, but it will get you home.
If you power off the bike and jumper the green service connector, then power on the bike, the FI indicator with cycle through the stored fault codes.
Note that these are stored fault codes which may not be current unless you cleared the previous stored fault codes.
It will blink to indicate the fault code number.
Fault codes can be two digits as well, so the FI indicator will have a slightly longer blink to indicate the left digit (tens digit) then the shorted blink for the right digit (single digits).
The service manual doesn't elaborate on the operation of individual components.
For the fuel pressure regulator, a frequent side effect of a failing unit is excessive fuel being injected into the engine. Up to the point where it fouls the plus and collects in the exhaust and drips to the ground.
The RC51 used 50 PSI fuel line pressure.
Due to the "customized" environment the engine is in, that's going to be hard.
If it has a power commander, you might could search and download a map matching your exhaust and mods.
If it was a bike, I'd say take to a power command location and dyno it for a custom map.
