I've been running a Proto E85 tune for at least 2 yrs now with no problems at all ,all i did was the 83 lb injectors + tune with all my other mods with great results & love it ,it's like running MS109 but instead of paying $15.00 a gallon it's $3.59 a gall.Pretty sure i'm one of the only 997tt running it in Socal ,for me i have a station right buy my house which is key to choosing it.You can always run regular gas just don't hit the boost,i will probably upgrade the whole fuel system (pump ,lines & even bigger injectors)next as i know my tuner says it wants even more gas.Milage is def affected if your lead footing around prob 12 mpg. The guys at BBI are on top of this type of mod for sure,& with more stations popping up in Socal i'm pretty sure there will be others on the road around here soon, being able to switch back & forth without a laptop would be nice & Todd told me he was working on it,so hopefully Proto will be to offer that soon.

 

excellent thanks. thats not too bad.

 

Is protomotive a vendor here? I tried contacting them but havent got any response to my email?

 

EPL in CT will be doing my e85 conversion and tuning shortly, they are relatively local to the New York area.

 

E85 is good stuff. having proper fuel delivery is a must, you use ALOT when running 30psi at redline.
