This could be a solution to warranty issues because of chips.

Superchips is coming out with a sililar prduct to replace the chip. I am sure Ford will engineer a tell tell for its use. I don't know how user adjustable it should be though.

The microtuner. However it is no good on highly modified trucks.

I know the Superchips microtuner will not allow adjustments to timing and fuel. The product above says it does. It will be interesting to see the results. I would love to be able to make those adjustments for the simple fact that I have been fighting the warm/cool weather tuning problems for the two years that I have been a Lightning owner. Maybe when I get my Swanson 4 way he can take care of that problem for me, who knows.

I am not saying I am capable of making those adjustments safely but you never know...
