OP, it takes a long time for the cost per gallon savings to pay off the cost of the larger fuel system and lower MPG. This isn't for fuel economy. It would take a long time to break even when you figure the cost of the re-tune and larger fuel system with the lower mpg. You can make more power, but I wouldn't expect more than 10-15whp out of it. It would allow you to run a little more timing. That's about it. If you're boosted, you'll see a much larger increase. Personally, I'd get a good meth kit. That way you see 90% of the benefit of E85, and you can get gas anywhere.
