    Hello all.

    Been looking at doing the N249 Bypass purely as a way of removing the pain in the ass box ontop of my spark plugs which makes changing them time consuming.

    Ive read about the Pros and Cons, and it seems a sensible upgrade.

    Does anyone know if the MTM tune would be affected by this being removed? - I dont know what PSI my turbo is running until i get myself down to Rtech in a week or two.

    MTM tune is no different really to any other tune if we're being honest, ancillary parts still do the same job. I can't see that it would cause you any problems at all :thumbsup:
