cheack that the trottle shuts proply and there is a lil slack in the trottle cable, it want be amzingly faster but you should feel it pull more in the gears. Like you say its not running proply so its not going to be making it feel faster yet

sounds like an air leak to me, did you replace the gaskets between hte 2 halves of the inlet amnifolds, and use gasket sealant?
and did you do the same for the TB to inlet plenum joint?

proper gasket paper will be ok, however you standard A4 printer paer wont quite cut it.
if you make sure it makes a complete seal, you could use the clear sealant you mentioned

well 2day i gave it a good blast, and didnt know that the power was way up the rev range like 5,300 upwards, and yes OMFG its like a mini turbo lol.
and it does pull slightly better from 4000 rpm.
thanks for your helps guy, well chuffed with it now

due to the fact that a janspeed 4-2-1 manifold really improves low to mid range performance i should think that is why i see a bigger gain from 4000rpm onwards
also what air filter set up are you running?
