E85 tune?

We gain 70 or so on E50 over 91 on stock boost. You cannot run full E85 with the factory fuel system

Why, cause not enough flow?

Because there is not enough headroom

I don’t think anybody here has done that yet.

Lethal Garage in Temecula CA makes a flex fuel kit for cts v. May need to change injectors, I haven't figured it all out yet.

How easy is it for you to find E85 where you are located? It is so hard to find where I am at and it is expensive.

I can get it down here near tampa and its damn close to 85. I forgot what the price was right now

Yeah, I have a 45 min drive to the nearest pump.....

can just get some 44 gal drums and fill em up for storage for track days, ive done that and even used e85 after sitting for couple years and its fine, just sit barrel up on some wood blocks and i add in a e85 treatment bottle every 6-12 months and just open it once a month and use a alloy tube and swirl it all around getting it moving so it stays good

I would consider that if I had a detached garage or shed, but unfortunately, I do not. I thought of putting a tank in the back of my truck to store a little extra. I also was sure how long it would keep. Thanks for the heads up on its longevity.

Is the E 85 treatment something to inhibit the attraction of water?

this is what i use i dont think it does specifically, i even just do the drum cap up by hand so it can breath a little when it pressurizes in the heat of summer and i still havnt had any issues with it over the years with water, i can mix up the drum and do a test and it still shows within a couple % ethanol, even my E98 i last got when i done the mechanical ethanol test with the measured tube and add water it only showed maby 1% water after couple years but that could also be the little error in the test so i class it as good
Ethanol Fuel Treatment (EFST)

There is ONE singular station within any reasonable distance. It's about 35 miles away and averages around e74 and last I checked was $2.98/g.


I purchased a 55g drum and hand pump, have my own makeshift gas station in the garage. The downside is I don't have a truck/trailer so I have to load up a bunch of 5g gas cans in the V every month or so. Still worth it.
