    first,, are you sure it has lost power,,, have you changed your brand of juice? the only thing I can say is,,, airbox mod, new air fiter/ new plugs, I use bosch super, and GM dexos2 oil,, also mines is loads better than when I bought it,, injector cleaner,,,redex.

    Vehicle : Vectra

    Trim : Design

    Engine : 1.9CDTi

    Year : 2005

    Mileage : Lots

    Default

    Do you drive it really gently all the time? Vectras have 'learning' ECUs that will adapt to your driving style. If you treat it like a bomb all the time, it will reduce power. Give it some miles and open the taps up, see if it improves.
