Eflexfuel Reviews

Super easy to install app works

Super easy to install app works perfectly on my 2016 grand cherokee 5 7 hemi it definitely has more power and i pay 1 90 a gallon here in Louisiana for e85

I installed two kits

I installed on kit on my wife s SUV and was impressed with the low end grunt and greater horsepower that comes with the eFlexFuel product Bought another SUV and got the same result Plug and play The mileage drop is more than offset by the I m saving buying 100 octane fuel at 2 59 per gallon

Best investment I ve made

Best investment I ve made I drove a Prius as my work car so I decided to convert and start saving money filling up Amazing how much money I ve been able to keep every full up My Prius even feels healthier with a pep No regrets wish I had done this sooner

Amazing product

Great product very thought out works flawless I love it so far Fairly easy to do and doesn t take a whole lot of time They answered my questions fast and actually answered them so it doesn t leave you guessing They also reached out to me about my car just to talk about it and talk about it which was a nice personal touch let s you know these people are true car guys and gals and that they are genuinely proud of their product and happy to see people that have it in their cars enjoy it

Bought the kit for my 07 mustang gt and

Bought the kit for my 07 mustang gt and im not disappointed at all I am full bolt on and now with e85 it definitely made it alot faster just with this easy plug and play kit I definitely recommend this kit

Quick shipping from Finland

Quick shipping from Finland which seems impossible Well thought out system and easy to install Surprisingly simple and the app works well to monitor the system

Engine purrs now

The package came from Finland and had everything needed and more My car is only 4 cylinders which was on my order but they sent the wiring for up to 8 cylinders I will keep that on hand in case I want to reinstall on another car My wiring harness was difficult to get off until a mechanic friend told me the best tool to use then it came off easily The installation videos were enough to get me through with the help and tools of a couple friends but more detailed explanation in English would have been helpful But I didn t call the hotline until after installation when I realized there was an app available which took longer to connect than expected The tech guy told me to wait longer and sure enough it worked Engine runs so much smoother and quieter now and I am enjoying the increase in acceleration trying out the 3 modes of the app and knowing what percentage of ethanol is in my tank
