I have been reading the MAF threads in the Group Buy Forum. Have you bought the ProM yet? I would love to see a dyno comparison using both units, but that doesn't seem likely to happen. Like you, I don't really want to be a pioneer on the CnL. Obviously, I don't care about comparisons on a Mustang. Put that baby on a Contour!!! Until I have dyno numbers, I'll just wait. I'm such a wuss.
