e-85 or 93
 
Im getting my car tuned on the dyno next week. I bought stainlessworks long tube headers and x-pipe. Also bought a LMR cold air. My question is to tune .with e-85 or 93 and has anyone tried e-85 with good results.

I went through the thread earlier and I don't think there is much difference. However, I have been told that Mobil and Sunoco offer the best quality 93-octane and Cheveron/Texaco add Techron to the gas which will affect the tune.

Thanks guys. I think im going to run 93. I was just looking to get a little extra hp. I bought a lmr cai and stainlessworks complete exhaust, it should be here this week.

Manual explains proper gas to use and gas not to use

None of the engines on the Camaro are e85 compatible. Ethanol fuel will eat through some materials in an engine/fuel system not designed to run high concentrations of it. DO NOT use e85 unless the manufacturer says its ok.

I've looked around here in San Diego and haven't seen any gas over 91 octane :( Still researching though...

Mill the heads to run 12-1 compression and run e85:headbang:

I wouldn't. The engine has to be specifically built to run e85, you would def do damage

Can you elaborate or show where you found this? I have used Chevron for over 10 years almost exclusivley.
How does Techron affect the tune? This is confusing as Chevron is a Top Tier gas recommended by GM.
If there is better 93 to run in it I would like that to be substantiated.
Thanks

:word: Everybody, read this! Do not put E85 in a car unless you are prepared to replace some parts with E85-compatible components. If your car is not running E85 out of the box, then you have some building to do before it is ready.

You can say that again.

not necessarily. ideally, yes you want to ensure you have the proper fuel lines and other requirements to run e85 regularly as well as tuning for e85. running a stock (gasoline) tune with e85 in the tank is asking for some trouble as the two react differently.

not megga, but larger injectors would be on the list of things to change over
