| How about checking the fuel pressure? Last year mine was ok when set up on the dyno then over the course of half a season the pump started failing, giving me no power, white plugs and finally a clucked engine come Snetterton.
A quick way is to check that there is fuel coming out of the return pipe, as it will prove there is more than the 3bar regulator pressure....
If that's ok, whip out the injectors and check they're ok, and/or swap front and rear to see if the white plug moves, if its only one plug.
