Hey all just thought i would post this. Just put a de-cat pipe on my zx and now she dont pull so well. use to pull like a train from 70 (I know the top end revs will be better) but at the moment I'm pretty sad. The engine seems to have lost its character. maybe I willl get use to it..... will i? 'Im going to have a long hard think. Maybe it will all be ok.

Maybe a ECU reset will help too.
Disconnect the battery for like 10 minutes or so.
