Re: 74mm Throttle Body, surging idle
My car sounds as if you have the same Mods, I'm am getting 211.4 at the rear wheels.
Look at my signature below to compare. I have 2.75in CAI pulling air from in front of the radiator and I kept the screen in the air box to catch any junk, but is as far from the intake as I could get it and still have at least some protection after the K&Ns.
