2FAST7S

I cannot rev past 2.5k rpms while boosting more than 4psi or so...It either dumps a boatload of fuel or cuts ignition not sure but i did notice my omp voltage on the sensor check feature on the PFC commander read 0.00 and highlighted. My question is could that be like my fans(they somehow got turned off during tuning when we started having unrelated issues), something that can br turned on/off through the datalogit???
