If I add HHO gas to a 2011 GMC 5.3 will I need to add a EFIE?

I only plan to add a starter kit wet cell just to see how it works. I already have a custom tune on my truck.

For your 2011 GMC you will need some type of enhancement or you will not see the MPG gains.
An EFIE is one of your choices.

Please read hydrogen car conversion to understand this further.

You can also contact us directly, please include your GMC model also.

Thank You
