Default What kind of MPG are you getting on E85?

Anyone with a boosted application actually tracked their MPG on E85?

I enjoy just driving the car around and won't be getting on it all the time. Wondering if 10mpg is possible with this setup on E85?

365ci LS2
LS6 Heads (stock)
LS6 Intake/Stock Ported TB
LS6 cam
PTE T76GTS

Tuner is... okay... he'll see this

13-14mpg.

You should have no problems hitting 15 with a decent tune.

I was getting 14-16 with my 5.3l on E85:224 cam, and 112 Maggy. This is in my 3900lb (with me in it) S10 with 4.10 gears and a 26" tire. I get 21mpg in the winter as I run 93oct.

On my 9:1 compression LS2 in my GTO I used to get around 22 average city/freeway mixed and when I switched to E85 it dropped to around 15-16. I guess I could get higher in general if I didn't like to hear the turbos spool so darned much. LOL The Camaro I couldn't tell you the drop because when it comes out it's just getting beat on.
