Default Since De-cat

Hi everyone,

Need a little help. I've just bought my first scooby, A 1997 wagon.

I have just fitted a De-cat pipe to it but seem to have gained a a fault since doing this. The turbo doesn't seem to surge quite as well now when on full throttle. If I drive it gently up to about 4000 rpm it runs great but when driving hard through the rev range the engine apears to holding back slightly. I have checked to lambda sensor which seem ok. Is there anything I should/could do to sort this.

Thank you

Paul

You'll need ecu mapping.
