Why did it only run 30 psi on the rollers?
Great figs by the way

should be over 480 then on the road with the 2 psi
im as happy as a pig in sugar
the figures confirm to how it drives on the road not much torque but a load of top end power

yeah would imagine it wolud be over 480 on the road
do you have graphs?
where the car seems to make the peak torque seems a bit odd tho....
would imagine it "should" be earlier?

torque slowly rises up to 7k but power just keeps going right to the limiter. 5.5k 310, 6k 360, 6.5k 410, 7k 460 and 7.5k 472

if the boost wasnt capped peak torque could be made lower down but bhp at the top might suffer..

1st to 2nd is the only tricky one to keep in v high power but it spins anyway so whats the difference. i love it

....like you say it sorts traction not the perfect yb but a perfect road car i bet without the need for throttle control....no different to my amg except the engine is perfectly engineered and traction control caps power for traction..which is alot 
...you have a compromised engine i have a compromised shell ...although from 3rd i get full use
