needs a proper live map including cold start etc for a t4, think MSD are around the £500 and they will need the car for a few days at least.
to be honest, if you are only wanting 300-350 hp then your car will be horrible to drive on a t4 turbo, better off with a t34. it will be a lag monster on a t4
a t4 is a 500/550hp turbo, but your 205 block probably wont like it!
my advise is sell the t4 and buy a t34, then get it live mapped or go for a decent off the shelf chip
