New numbers with Performance's tuned exhaust at 8000 ft:

All this great stuff and not a single knot faster!
Peter,
So, OK numbers. A 1.7 gph improvement (8.6%) is the
same performance on less power. What happens to the TAS when you increase
the rpm to consume the same amount of fuel, 19.8 gph? Have you considered
the difference in dew points on the days the test were run? Were the
gross weights and CGs the same? So many questions, so little
time......................................
