hi guys

my mate just brought a t4 as in title just wanted a few questions answered if any one can help ?

first of there is a slight problem starting at first wen cold it takes about 3-4 seconds to start but once warmed up its fine? it also feels a bit hesitant at around 3 thousand rpm nothing bad but just woundering if there are any common faults that can cause this?

also the car has been mapped at sumpoint i think as there is a dyno printout for it with 223hp at the wheels.

with all that aside all is well will be given it a full service asap.

my next question is how do i get more hp out of it? im looking to get around the 300 ish hp mark whatever the best bang for the buck is with out spending to much money e.g 500-1k

anyhelp will be much appreicated

cheers guys
