Excellent Protuct. Every availble program does exactly what is supposed to.

I received the F5 quickly. I read the directions and plugged it in my truck. It is very simple to use and I tuned the truck quickly. Now driving it is different. It is peppier and my fuel average went from 11mpg to 16mpg. It's a Dodge Dakota with the big v8. I will set it to towing when I pull my trailer and I'm thinking it will have better power on the hills and better mpg too. I would recommend this product to anyone.
