I would only be interested for getting an HP figure. Probably only a few times over the years. As for rates, what do the local dyno shops charge for their two-wheel drive dynos? 50 an hour? I'd be willing to pay around 75-85 an hour, tops.

As far as wideband goes, I'm going to have that covered. I've been doing some research on wideband units and I think I'm going to get one when the money permits. Knock and timing are good, in fact I think the only thing the wideband does is give you peace of mind letting you know you're not too lean, and letting you know if you're trying to run too much boost- if it takes a 10:1 afr to keep knock and timing in the proper range at 21 psi, you'd probably be better off running 12:1 at 19 psi for more power. That's how it was explained in a thread on nabr- you're changing from just tuning for knock and timing to tuning for knock, timing, and good afr.
