I’m leaving a five star review only because it works.
I saw my gas mileage go up by two or 3 miles average just in the first day.
Don’t pay for expedited shipping as it’ll still be late and you’ll waste your money. Stick to the standard shipping.
OK, I am impressed!
I just returned from a trip in the Smoky mountains of Tennessee in my 2013 Nissan Frontier Pro-4X.
Before the Nissan Performance Chip I would get 14-15 mpg.
The same trip with the Nissan Performance Chip I got just over 18 mpg. Wow!
Also, from day one, the the performance increase has been very impressive.
I plan on getting a Nissan Performance Chip for each of my two kids. They both drive Nissan Frontiers.
Thanks for a Great Product!
Performance has improved. I’ve got no complaints at all.
Original owner of a 2015 NISSAN Frontier SV King Cab 4 cylinder, automatic, 68500 miles. Previous mpgs with Amsoil 5w\30 were;
BEFORE:
city = constant 15-16.5
highway= 18.5-20 (auto cruise)
AFTER:
city= constant 17-19.5
highway= 22-25.99 (auto pilot)
I noticed after approximately 150-200 miles the algorithms took a set and my personal test with my complete driving senses revealed performance enhancements in stronger shifting, a throatier exhaust (stock) and substantial torque for a twin overhead cam engine.
My final test will be when I tow my 2016 -20 foot LANCE Travel trailer when weather is in my favor. I know my stats on the trailer from previous trips so this will be a journey of various surprises.
Also, I use top tier gasoline MOBIL PREMIUM 97 octane or other top tier if Mobil is not available. The reasoning is that before I retired from California State Emissions Test and Repair Bureau as a Blue Shield/ Gold Shield station specialist I was privy to important data from customers cars who would not pass the California smog test. That being said, I test vehicles on the dynamometer for exhaust values for pollution standards. I noticed through the years that many vehicle owners opted for the cheapest grade and/or price of gasoline. When you see the early on set of premature carbon in small orifices that set engine codes you see why a higher detergency is long term investment.
I am sure i will love it
