Those are awesome numbers. No denying it. Quite impressive.
However look at the graph. An Oversized turbo making just big peak numbers. Nothing under the steep curve & that lag is huge.
Impressive peaks like I said, but no powerband and you have to wait for it to peak. I can see why his times are slower than the power indicates.
Call me a hater if you like, but there is more to driving and tuning then just peak power only!
