Robert,

the srt well report throttle position thru obd . you should be able to turn it on ,take it for a drive and see if the throttle is opening fully when u floor it . if your foot is to the floor and your obd is showing anything less then 99% the accel pedal is probably the problem . also it well show iat's , if there over 200 degrees your ecm well shut down your supercharger .
