New harmonic balancer swapped in - the old one had definitely spun 5*. It still feels down on power compared to the stock 3.0L internals. I may need to advance the cams to pick up some more compression, but I guess I'll drive it some for tuning first.

Charlie, based on my tables, if it continues to feel sluggish, would you visit the dyno first..... or roll the cams forward before wasting money on the dyno?

Brendan and I noticed last weekend that it wants to run at 75-80mph on the highway.
