I personally will be doing all the piping/dual pop upgrades and going this route. Saw the install in Elliot's car and it's super stealth! You use the Hour and Minute buttons to change maps and since my clock doesn't work anyway (as many of you also suffer from) it makes great use of that space without cluttering up the dashboard with more electronics. As stated earlier it does take more E85 vs 93 octane so you will need bigger injectors at the absolute least. Fuel pump (Walbro 485) that is E85 compatible is highly recommended as the stock pumps don't like the Ethanol. I am running 555cc Nismo injectors and they would only be good to about 400hp (exactly what I'm already making on 93 octane). So to see the true benifits bigger injectors and bigger turbos are needed.
