I purchased a Forge splitter Valve and run it in Atmospheric for a week or so and was not really happy with it so put the OEM valve back on.
I know want to give it a run in Recirc mode and am wondering what setting i should have the spring at?
i believe i was running it at 35 turns from fully anti clockwise in Atmospheric.
should it be the same in Recirc? my car has been mapped but it is an unknown map that was done by a local garage for the chap i bought the car off so i do not know what boost i am running at which i guess determines the spring tension?
i know where he had the map done so i guess i should just ring him to see which one it is. hes an independant BMW specialist so i take it he would use something like CC or Revo rather than a map that he has made himself?
forgive me for the stupid question but im a bit of a novice unfortunately.
