not the old tuning war again, it says on angel tunings website "up to the bhp stated where possible" every car is different so putting a map on with no RR testing can only be estimate, they offer a money back guarantee if you don't like what they have done.
if people don't want that sort of map then go to a different company that uses a RR.
it like buying a tin of carrots and moaning after that you wanted fresh carrots. look at what your buying before hand decide what you want,
