Local group had a charity dyno this weekend so I went to support the cause. Ended up putting the truck on the rollers with my drivability testing tune. Top end was turned down via fuel (so I thought ) timing and pressure. Bottom end was turned up as I'm no longer too worried about the bottom end anymore. Anyways, learned a few more things about the way these trucks react to tuning and ended up making a smoke show and embarrassing myself regarding that, oh well. Truck kept picking up power the more load he put on it but 3 runs was it.
