1. EML light coming on at high revs due to high pressure in intake manifold

    R53 General
    So i recently had a 17% pulley installed on my facelift cooper s, and now when revving to the redline it occasionally throws a fault code, which reads as too high biometric pressure in intake manifold, if anyone has a solution to this it would be really helpful.
  2. Which plugs should i get?

    I am having my 15% Kavas supercharger pulley fitted tomorrow, I have seen some people have said you need new spark plugs, which ones do you all suggest? Thanks in advance.
  3. Kavs Ported Cylinder Head

    Engine & Drivetrain
    Has anyone had any experience with a Kavs head? His heads are cnc'ed and he claims he's made 280-300bhp with them. Kavs seems like a great guy and his products are top notch, but I havent found any feedback whatsoever on his heads….anyone? Cheers, Matt
