[1forI]

Thanks guys. This is helpful. I had read that thread but not the newer posts. I'll revisit it. My confusion came when I saw the big power gains on pump gas, but then someone "associated" with BMS said that it was only recommended for turbo upgrades (which makes sense, power-wise).

I have most power mods (minus fmic on the way) but am limited by 91 octane. I mix in 4 gallons of e85 and am very happy with the power, but since it's natural to want more eventually wanted to know my options for increased power and smoother delivery. Not really thinking about meth (yet) and not going to upgrade turbo because I have a lot of suspension work ahead that I'd want first.
