    turbo knacked???

    last year iwas on the rollers and got 220bhp. since then i have had a full turbo back exhaust and was hoping for around 230bhp. last sunday i took a run out to star performance with some guys from here and vvoc(i think) and only made 199bhp. could this be a weak turbo?

    do you have a boost gauge? If not I would advise you to get one. Do you have the two graphs so we can look at them. You may find the boost really leaking away now

    Fair enough.... Could be leaking boost somewhere? Was it the same Rolling Road? as some of them do tend to vary results a little! or, hate to suggest, your exhaust blowing somewhere??
    I thought I had a hole in my exhaust, turns out, manifold bolts were slightly loose.
