Have you checked the camblet timing, this makes them run off power, make sure you take off the alt belt pulle so you can see the actual cam pulley markings, the alt pulley bit is noturious for slipping and being out.

Get it on a rolling road to at least get an idea of the power figures.

How does the car feel to drive? Sluggish? Holding back? Plenty of revs, but you just don\'t go anywhere?

When you say it\'s slower than it should be, how are you measuring it?

If it\'s just a \"feeling\" then you\'re going to be a while trying to work out what\'s up with the car.
You\'re going to need to give us more information if you want to diagnose it.

Is the ECU bringing up a fault code?

Have you checked the cam timing?? If it\'s not coming \"on cam\" sounds like timing.

It shouldnt mind what gearbox is attached really.

Like J1400 has said this points to cam timing.

ive had a look at the timeing it looks like it may be a tooth out do u reckon that would do anything...
