i've been to Weston Performance today in solihull,put the cossie on there rollers

they have an awesome setup there,really impressive
they seem to do a lot of Jap stuff,

has anybody else used them before? do there results seem to be spot on?
my results seem to be pretty bang on,the boost hit the same levels as it does on the road,so seems good....although they are a little pricey IMO
