Did you do the idle screw the way I stated above ? that is the only correct way to adjust the idle
You may have a Vac leak

A datalog would go a long way to help with your problem

The Ford Racing tune for the jrsc and the PW tune for the PW is only made for an all stock car with just the SC added any other mods added will change the tune

I hope you have at least a wide band air fuel gauge and are watching the AF , the PW tunes blew up a LOT of engines
