I have an E36 318is (M44) with a DASC kit.
I have read that I can add a "R POT" valve to the air pipe to the air shrouded injectors to reduce boost loss. Do you know if I can use the same valve as the one fitted to the brake booster vacuum hose as this seems to do the same thing, although I don't know if it can/how much boost it can take?
I no longer have the DISA system of course. How can I make a DISA simulator to prevent the error code? I read that you just need to put a resistor across some of the connector pins, but need more information on this.
I plan to change from the K&N pod air filter back to the original. Is there any problem with this?
