i no lots of engine builders map there own engines, what i am interested to no is who do you lot think is the best at mapping out there .

i would be looking into mapping a wrc escort cosworth engine in a rally car .
if i was to have a engine built to my builders spec that hes built many times over the years who would be best to come and map it for me ( could it be mapped in car and not on a dyno ??
it would be on pectal t62000

thanks steven
