The two we dyno'd had over 2000 miles on them...no difference.

A friend of mine that was at Carlilse had his '03 HEMI Ram 1500 RC 2WD
dyno'ed that same weekend and his pretty much pulled the same number.

His only had about 600 miles total on the odometer, so I suspect that
after a few thousand miles of run in time it may do better......

I told him the same thing Bernd just said
about this one.........

So yours isn't the only Hemi with a lower than expected RWHP ##, this
seems to be about normal for a stock Hemi.....
