    part throttle tps surge on steady pedal

    6.1 srt8 whipple 2.6L kit
    just accelerating normally, from 2nd gear up (doesn't do it in 1st), the tps will suddenly swing to 50% plus with a steady pedal. enough goes into boost and will spin the tires until traction control stops it. if it doesn't happen in 2nd does in 3rd but there it won't spin tires but really speeds you up quite a bit. car already had tune on it before i did s/c stuff, but i didn't touch any throttle or torque tables.
    any ideas on this? had friend his turbo ram would do this but only in cruise control.
