Default F4i runs likecrap

I've got a raptor quad with an f4i engine in it. Can get to run but pops and cuts out when u try to rev up and it hard starting. Has good fuel pressure, fresh gas new plugs, spark at all 4 plugs, bypassed tip over sensor and anti theft in ignition. As for codes it blinks 2. 7 and 9. I looked up and says map sensor, air intake sensor and engine coolant sensor. I tried a new map sensor and checked all the lines and they weren't plugged. Anybody else have this trouble? Any ideas?
