Is there a computer chip, or something, that I can install

Customer Question

Is there a computer chip, or something, that I can install on my 2005 Nissan Frontier Nismo to help with gas mileage and knocking? I use 91 octane fuel and that helps very little. I got better gas mileage with my old Durango w/ Hemi.

Hello, I'm Brandon - Nissan tech.There is no such chip out there that you can install and increase mileage per gallon.

Do not believe in any ad that claim will give you better mileage it is simply a lie.
Expert:  internal88 replied 1 year ago.
How many miles per gallon you are getting from your Frontier?
Expert:  internal88 replied 1 year ago.
I would advise you to install a K&N air filter to help increase the mileage and horsepower.

Do you have the 4 or 6 cylinders?

Make sure you check the tire pressure and maintain 34 psi in all tires.

You will need to keep putting 91 or 93 octane fuel to get rid of the knocking eventually. It will take a course many refueling to get of rid the knock. There are carbon on top of piston head.
