boost causing bog

sounds like either a boost leak or over/under fueling. most likely under fueling unless your FPR is boned. then youd basically be shoving fuel past the injector pintle.

another possibility is bad KVAFM. check up on the TSRM to see how to test it, youll need a multimeter.

ohming the injectors wouldnt be a bad idea either while your checking.

just another quick thought, check to see if your wastegate is working properly

good luck!
