Dave, first off thanks for the info, it is highly valued and taken for just what it is, some logs at various times, not a direct comparison, yadda yadda yadda. Still the data says a lot.

Question: is it common to see and extra ~400rpms of lag when stepping up to your race core, even if you're coming from the (already fairly big) deluxe core? Or does this depend on the turbo...i.e. a stock-frame turbo like the IX or 20GLT will see more lag on the race core than say a 35R?
