If I had e-85 any where close to me I would go that way because fuel economy is not what it's about if you play a lot lol. I can get e85 delivered for $4.25 a gallon and 100 octane for just under $10 per gallon. I was hoping ecutek would have come through while my Z was at SZ, but it didn't so I went with a 100 octane tune and I have no regrets as my torque numbers are stupid on 100 oct. I need rear tires
and now I get to think about what is next. I should have never taken a drive in Seb GTR!!!!!!!!!!!!!!!!
