you can buy an HP Tuner for 500, and while it won't address the starting issue, which some don't even have, you can adjust for E85 and bigger injectors. I've been running E85 on my car off and on for a few years now and love it. for me, the last time I bought E85, it was 1.85, premium was 2.60 at the time, so the cost is a wash, but for the additional 50 hp, I don't mind. since then, premium has gone up to like 3.00 a gallon and E85 is like 2.00 per gallon, so it probably is cheaper.
I love having the HP Tuner, and think everyone should have one, even if you don't know how to use it.
