I have a problem with what appears to be a tps or related problem when supercharger is used on both auto and manual trans. the supercharger dumps at 4000 rpm as the throtle body will not stay open have tried bbk,ford and same problem after time 2-3 weeks the auto is way harder to get a read onand now it will not shift to overdrive .No codes change tps and problem got better but still no overdrive.
any one running tci 3500 stall and superchargers with same problem let me know what you have done
