HPF stage 2 meth problem

New pump, new Solenoid and sensor is about a year old. On just the pump/meth setting, the car starts to Flutter and loses power on midrange and above. The boost gauge stays at 13 so I don't have a leak or the sensor going bad. The car doesn't seem like it's missing! On pump mode and race mode only( no meth) car runs fine. On race/meth mode, I think Everything is working fine but hard to tell.... I might feel some fluttering on the very top RPM range! Also if the car is cold like it sat overnight, I can get 3 to 5 pulls with the meth before car starts acting up... Once the car is completely warmed up I seem to have the problem with the pump/meth setting, Any ideas
