All an interesting read.... whilst we are on the subject of Mafs..is the 2.8hdi maf plug and play, as in no need to map in or cross wires?
Im sure the hks mushroom I use has made a difference... especially initial throttle response... but I'm on my 3rd maf now. I know cone filters are terrible for heat soak in summer but its simply a case of you can't have it all IMO. On mine The inlet is 3 inch with a silicone reducer onto the maf. I must admit that pipe going to the Turbo does look restrictive but I'm only running a stock gt15 so I doubt that the Turbo will need anymore air/flow than that pipe gives
