I’m on E85 now. I have 25 miles to empty can I just add 93 now ?

But 50 for me is a half tank. You at a half tank swap tuned and change to 93 from e85 & vice versa ?

So, not sure if I understand your last sentence but like I was saying yesterday I was planning to do the switch.

I had almost a full tank of 93 (at 240 plus miles to empty) in it and I got it down 103 miles to empty before having to get home because it was raining.

I’ll take it down hopefully later today to 60-50 then come home and load the tune in the garage. I picked up roughly 15 gallons of E yesterday morning so I fill up at home.

As I’m sure you are aware, the gas mileage drastically changes when you have E in the tank. After running the first 80/20 E through, it will read 145-160 miles to empty on a Full tank of E .

Hey, that’s the price we pay for the tremendous benefits you get from ethanol!

50 miles to E is a half tank for me lol. Now on 93 it says 11.5 MPG. A full tank of either fuel is under 120 miles to E.

I did the pulley swap. It was easier than I was imagining. Now I’m making 618WHP with a 4.25 pulley and 93 @ 10.6 PSI . 618WHP feels so slow compared to the 850WHP.
What is my fuel system doing for me now since I’m on 93 and low power ? Also how do I know if I have both my pumps running or just a single one ?

I think I’m going to order a 4.0 pulley. I guess that’ll put me at 12 PSI and maybe 650WHP or so

That’s a good question about both pumps running, I would assume both are also running no matter what fuel you have in the tank.

I switched back over to E yesterday, and was trying to run the 93 and E mix out, and top back off with all E, when I encountered a BMW M3….. I was chilling…..wasn’t looking for no smoke…..he just had to start something…..smh…. I Destroyed him!!!
And my ethanol content was only 61% because of the 93 still in the tank.
I love E85!
drive safe guys!!
