I have benchmarked my 408 stroker with all three Dyno methods, in my case I actually did a chassis dyno before doing the engine Dyno. I was happy with my chassis DYNO results 423HP and 408 ft/lbs of torque, however the DYNOJET doesn't help you with drivability tuning. I use EFI with the FAST engine control, this gives me control over fuel curves.I spent most of the summer driving around trying to get my fuel numbers right for the 2000-3500rpm range under light load. I decided it was time for an engine DYNO, this allowed me to control load at all RPM. The resulting number show the differences between all three methods. Motor is back in the car however I have not driven it yet. Looks like I loose 70hp through the drivetrain
