i see what your saying but on the motor run it was almost identical as it was before so it didnt richen up nor did it get lean it was still the same i dont have the sheet in front of me but i think it was 12.5 or so a little rich but i think it was the same and on the bottle it was i think 11.2 or so and i have a 150 nitrous jet in the fogger with a 125 fuel jet in the fogger and it ran the rich still so i dunno any other ideas would be helpful

Beat a pipe into/through the cat or cut them off completely. Gutted cats sometimes tend to cause more turbulent airflow. Noob opinion anyway 
. Just as an example. I gutted my factory rear cats (front were lost in header install), lost 5hp/12tq. Cut the damn things off (no front or rear cats now) and gained about 14hp/8tq over the starting point.

yeah it was the same dyno cause we only have one here in town so yeah it was the same dyno and yes the numbers are corrected. the only thing that is different is that before it was in the air and since my last dyno(the one where i dynoed 332) he's put it in the ground so what i was thinking is that he screwed up the dyno by putting it in the ground so i dunno any more help is appreciated
