I have to agree with you, my friend had his saph live mapped at engine advantages, they spent all day doing it, it had greys, ported head etc & a t34.55 & the best they could do was 397bhp & the turbo was only thing holding the engine back under the 400 bhp mark, With a .63 it would have done it no problem.

a t34 .63 can make 400 just.
i did make 400lb/ft with the .48 though
and broke standard boxes like chocolate
as for cr...std, or 7.5, i wouldnt go less at that spec
