I've got an AP Racing 4 Paddle item with standard housing and mines only got about 220BHP (If I'm lucky) I had a Stage One Organinc item that only lasted a few months

Its not to bad round town now I've got used to it, can still be a pain at times though (I have on my list of things to add a Hyd Clutch conv.) espcially if I haven't driven it for a while.
