ESS update.

I finally found the correct set up for this piggyback. This time I ran 100 octane, program two +3, the graph shows my M4 and my friends stock M4. You'll remember from earlier posts I was losing a lot of power after 5000 rpm running this program. Only difference now is the fuel. I have DP's and K&N filters. Also note this was on a Mustang "Heartbreaker" Dnyo. So on a Dyno Jet the numbers would be well above 500.

Isn't that what I told you back then? Can't recall if that was you I was remembering?

I've since switched to jb4 and logging data you can see timing just plummet with 91 octane with any increase boost so no surprise here

Yes 100 octane is the way to go with this tune. Much better than the 93 octane pulls.

Enjoy new found power band. Now you can take advantage of gearing and nice too end power to really out torque to the ground and accelerate!
