After every mod I usually turn my aerofroce gauge to read knock and HP just to see what ive gained from each mod and when I did my headers and tune the gauge read about 330ish HP so i assume it reads what it thinks the flywheel hp is, even then seemed a bit high. I did my gen v swap and just yesterday dropped down to a 3.6" pulley to see how my car would like it and it read zero kr at wot. Today i decided to see what it would read for hp improvement and i cant get it to get above 250-260hp. Car doesn't seem any slower except i do have a bunch of S**t in the truck so it is a tad slower than usual but not a 70hp drop. Is this something the aeroforce isnt very accurate with or do i just have a bad one? I know the torque reading is bulls**t. It was telling me that after i did my headers i had 470ft/lbs
