i payed £4080 in the end for it. but have found niggly little things i need to do

but as far as performance goes its brilliant i have only used it a few times as i want to give it a good service an get it on a rolling road so i know everything is ok before i decide to show it some serious revs.
it was advertised as a jamsport2.5 kit an 280bhp but i predict that is more around the 230-240 mark
biggest problem is getting the power down now.

how do you find yours? any driving tips?
this is my first supercharged car..
