The Digital Fuel Adjustment System By Punk Performance or DFAS for short. An interceptor performance chip. This unit is used to control air fuel mixtures on a vehicle fitted with a voltage out putting MAP, MAF, AFM, IAT, Hotwire or Vane Type sensor. It can also be used to intercept the Oxygen sensor amongst other uses.
I had a pun performance chip on my c50 boulevard and loved the unit, worked really well, just sad that it dies from poor wiring and was not able to repair it due to being filed with encapsulating fluid. Otherwise I highly recommend these chips. Keep em coming.
