I have an Advanced Fuel Dynamics flex fuel kit for sale.
Just download the app and you can see/read the E85 content % instantaneous.
Ran it for 8 months and realized I only ran e85 3 times through it. Can definitely tell a difference but I don't care about power that much. Best way to explain the difference is 3rd gear on E85 feels like 2nd gear without e85.
You do not need an e85 tune for this, or any type of tune. It's direct plug in play. Check out their website, I believe it retails for $900 brand new.
$500 shipped, everything included to run it. No missing parts.
PayPal, Apple Pay, Zelle. Contact me and we text directly.
Located in Las Vegas if anyone wants to local pick up.
