I'm boosting my 2010 m8 with cutler stage 1. I will be running 2000feet at home and 7000-9000 I'm the hills.I live in Alberta. I'll be running the 09 low comp head and would like to stay on 91 octane fuel. I've heard ov the 3 degree e key. Should I be running it as well? If I wanna run 91? Any help would be great. Turbo shud be installed on wed. And will be riding sat in the hills. Just wanna have everything lined up for the first trip. Thanks Jeremy.
