I am using 95 octane. Though many say it is more like 91. But that is the best we got here.

I would have posted the dyno video and graph, but stupid iPhone showed an update to ios6 without giving me heads up that I needed to back up my phone 1st. So i lost everything including my entire summer memories!
What have you done to the engine so far for 390 WHP?
