I got a supercharged for F150 1999 and I just found out there was a diablosport chip in my ECM there is a switch with cord as well, but it isn't connected to the chips port, is there a reason for that? its a delta revolution chip, I know the switch is for different tunes, but is there something missing? hit me back

 

I had the single program chip. Had lots of tranny pressure issues. Changed over to an xcal2 from Troyer, picked up 23RWHP. Also lost the tranny issues. Was a proponent for diablo at one time, now I wouldn't waste my time.
