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.
