Thanks for the feedback Mark. Frankly, my main objectives in doing the dyno were to (1) check that the engine was operating within expected parameters and (2) get a baseline before installing any drivetrain/engine mods.

Regarding (1), regardless of which corrrection factor I use, it apppears that the engine is developing at least in the range of 601-622 flywheel hp and 574 to 594 ft lbs of flywheel torque which is consistent with dyno data from Chrysler, your data and the data from other 2008 owners who have posted baseline dyno data on this site.

Regarding (2), I guess the only important thing is to see if the Belanger system actually results in a net increase from my baseline. I will report on that later.
