Back from the rolling road.

The engine has picked up another 25lbft, but also lost 25BHP at the top end.

Speaking to my mapper and also looking at the logs from the two sessions, my mapper took 1.5-2 degrees timing out, which is why the power has gone down above 5500rpm.

I think with one final mapping session to bring back the top end and we will be there, it's looking like it's a 490lbft @ 3700rpm and 460BHP @ 6500rpm package, which is just what i was hoping for. Mid range is nuts, there is no need to change down from 6th at cruising speeds, it just goes, very impressive IMHO.

Peak boost on the rollers was 1.85BAR @ 3500rpm, it pulls 1.95BAR on the road at the same rpm.
