    2015 coyote with whipple stage 3

    Hello,

    was hoping someone coul help me troubleshoot .

    coyote swapped fox body (stock 2015 engine 5.0), was running great last season. decided to get the whipple supercharger kit with the 3.875 upper pully (11ish psi), 132mm throttle body, FID 1600cc injectors. c16 fuel. 5" CAI

    pretty familiar with HP tuners but not an expert, downloaded the stock file and saved it. modified it by putting in all my injector data in and some spark adjustments etc. but the idle is throwing me for a loop. ive tried playing around with everything and just cant seem to get it. on start up the car revs to 2500 and hangs there as it slowly keeps climbing up to about 3500 and stays there untili shut it off. tps says 12% at the point when the pedal tps reads 0%

    ive played with the torque factors a little bit , i can get it to idle about 1200 but surges crazy between 1200 to 2500 back and forth. I know im most likely missing something stupid, any input is appreciated.

    thanks
