that'd be good kev. yep im using a begi fmu , on a t4 hybrid. its a bit weird as, if i keep my foot planted from the word go, it'll be fine and pull like a train. but if so as yesterday, im on the a12, and go to increase my speed from say 70mph, ill more than likely get a quite sudden and voilent cut. ive not yet had the car on vag com to confirm it , but my idea was the maf.. not to keen on going 4" maf at the mo, as it entails a whole load of other stuff , which at the mo i dont want..plus theres more than enough power as it is.
