Old thread,but bored. I was running some of the numbers thru wallace calculator and they are surprising close. Makes me fee better about potential of my combo. 1650 at 950 to 1000 hp(conservative compared to desktop dyno). Numbers ar better than I am hoping for,hey sometimes a surprise can be good,I guess. Now if can get some runs to get to where car(AKA tuner) is doing job right and see how close.
