I read it all and that's my understanding too but I don't have a good source of e85 every where I go. There is one local station here that has it but its out of my way. And being navy I can't be for sure where I will go next and if they will have e85. But 93 octane has been everywhere I have been and good ole -20 windshield washer fluid has too. So I figure I should be able to rock 10:1 and the boost I love with 93 and meth Injection.

 

Looked up boost LS2 setups, they run 11:1 and seem to be snappy as hell. Also ought to give you some tuning insight.

 

I would love a fast truck that still got decent mileage. I get a touch above 12 in the city and 15 on the highway on 93. I'm still on MAF so I can't do lean cruise. On E85 though, I'm at 9 city and 13 highway, I can watch my gas gauge drop when I get on the gas but it does feel much stronger.

I noticed a 1-2 mpg drop when I put catless headers on.

 

Is that running just 93 octane? That would be pretty cool to get into the 11s with that.
