I recently got into doing my own tuning. I finally had a chance to compare 91oct vs e85. This is on a S trim v2 with an air to air intercooler peaking at 8lbs of boost. 91 oct tune was 17 degrees of timing and my e8 tune saw 23 degrees. It made half a lb less boost than my 91oct dyno run (weather). Stock 115k mile long block.
Running a single walbro 465 and its only at 78% duty cycle.
