I do not honestly belive E85 will be a happy fuel with nitrous.

Works just fine in my experience.

May only be rated for 105 octane but the anti-knock rating is 116 on top of the huge cooling affect it has.

Using a 82n-91f with e85 and 6.25 fp it was very fat.Surged real bad and my wide band was showing 8:1
I pulled some jet out and lowered the fuel pressure to 5.75 and will test it again tomorrow.

What nitrous kit do you have?

From what I see that tune should have worked. Is your wide band on gas or ethanol?

K, my Bigshot with a 6 an feed on the Nitrous side did not flow what its rated after a certain level. Fuel sides always flow good.

That makes a tune rich quick.
