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? |
I have the following:
Full custom catless x pipe.
Eisenmann race exhaust
Active autowerke pulley
Afe direct filter
PP-Performance tune
