For anyone looking for performance over anything else, the FOOSE performance ( #chipfoose @chipfoose)is the way to go. The performance gain and throttle response is better than any single bolt-on part I’ve ever seen. Your MPG will be better than ever before but it will take more than a year to return your investment in fuel saved.
This is taking into account on non-factory ECM tunes the PFC allows more of your fuel to vaporize in the cylinder. In our testing, depending on the fuel, 10% never vaporizes or burns in the cylinder. Therefor we recommend checking or returning your ECU for the PFC. In most cases you can lean your WOT for even better gains in performance without worry of cylinder lean out.
