    There is no educational value to this thread, just for S&G's I'm curious what kind of MPG some of you are seeing with PI?. I'm running the Stg 2 LPFP (no PI) and upgraded twins, and I frequently see 14-15mpg with normal day to day driving (which includes plenty of WOT pulls).

    PI only runs under moderate to high boost, so you shouldn't see much of an impact to your MPG. Actually your MPG reading may go up because the fuel consumption being reported by the DME does not account for the additional injectors. :) (Obviously you're not getting improved mileage with PI)
  3. WOT would probably make it where you could watch the needle drop.. but, daily driving I doubt that the PI would change a lot
