E85 vs 91octane; how much power is left on table with 91?
E85 allows more boost and timing along with a larger tuning window but your goals are far below that need.
Don't listen to the guy saying boost is boost when he doesn't run E. When you want big power then you make the jump.
Because my car is off road, being able to fine tune off idle is critical. Would 80lbs allow better refinement at expense of total hp?
