COLude

I am trying to tune my lude and was wondering where my fuel pressure should be at idle and at WOT with 6 to 8 lbs of boost. I am using a Walbro fuel pump and a Cartech FMU. My pressure is at 40psi at idle which is fine, but I have yet to play with the FMU. Also, I am running colder plugs (NGK ZFR7F-11)...where are you all gapping them? .035? Any advice would be helpful.

35 is okay for gap. ditch that fuel pump, it cant hang with the high pressure needed in an FMU setup,it will lean out as you start to get into some boost. start with the bleeded on the cartech all the way closed and see how it runs.
