Wouldn't say perfect, as they still seemed like semi-bogs. 1.9 60fts. Best time 13.63 @ 167. 3/4 tank of pump fuel with NF. Videos look like slow reaction time, but it's just me waiting till I'm at the right revs before launching. Didn't care much about the car next to me as I was racing for time. Our track is 5500ft above sea-level, so the time are slow.
