Rollers are for tuning, you can't compare figures from different sets/makes of rollers. Seemed the lower power cars were reading fine but the higher fwd figures were strange. It would have bee interesting to get some whp figures because it seemed the flywheel hp calculation might have been the cause. At the end of the day its not possible to do a 12.9 with 235hp :)
I'd of liked to sample the afr, boost pressure and inlet temps too. I know on my car if the inlet temp goes over 45 its set to pull timing and add fuel to keep the engine safe.
