Yeah, if you guys have true 20-21psi - then 530whp sounds about right and hence about 600hp at least (if not more) at the crank. Looks like you guys are highest so far.
P.S. Just wait me crank up my Bpc Stage 1.5 to 20-21psi - and then we'll see
Maybe I'll be lucky to get to 550awhp
P.P.S. Is there a tune for E40 at BM3, have anyone seen something like that? Just wondering
