Hello Gabor,
sorry but in my opinion those figures are way over what is achievable in real life, and as such I highly doubt the accuracy of you dynos..
I base these arguments on three M60B40 that have been dynoed on different places that have been proved to be very accurate. All of them were dynoed before and after the changes were made.
Stock the engines made 280...290hp. With reprogramming the other one "live on dyno", it made slightly over 300hp and couple of Nm under 400Nm. One with "ebay chip" made 310hp / 420Nm (though that one had highest dyno figure in the first place). So realistically these two made same hp after chipping, though the "ebay chip" never got as good behaviour to the engine as the "live-mapped" one.. And both had "reworked exhaust", otherwise realistically stock engines.
The third one, also with "reworked exhaust" made roughly 350hp / 430Nm with heavily reworked heads and grinded cams etc..
Thus, I'd say roughly 300hp / 400Nm is limit with pump-fuel for stock M60B40. B44 might be able to give 10% more but that's about it, unless you start playing around with heads..
M60B44 with worked heads / cams and proper exhaust might, on the other hand, get you quite near 375hp / 475Nm figures on a streetable car.
