the power it made was ok but threw up an issue with the balance vis. i sorted it yesterday and its the best my car has ever gone. im just gutted i didnt know about it before, but this was the reason i put it on the rollers to show me if there were any problems before i get it re-mapped, (and a good job it went on them!.) i would like to know what power it was robbing me of.
are you still using the existing exhaust manifolds that came with the car.if you are i would get rid of them as they are so restrictive.i would put on the ones from janspeed and replace the decat to a sports cat.
as i have noticed in your sig that you have a janspeed exhaust on there

Ah right, well that should make a difference, especially if it feels faster. What exactly was wrong with it? I guess if you put it on the rollers to find any problems then you have achieved a good result. Glad you sorted it.
