Tone ring mod/RokTek sensor is fine (I have them), but if you really want better performance & fuel economy you have to modify the fuel map by either intercepting the signals on the sensor bus with a fueling box (hardware) or by altering the map inside the ECM with a fueling programmer (software).

 

What type of hardware fueling box would you recammend ? I don't need any more power although that is always a bonus. Better fuel economy is my main concern. Also would like to have something that can be removed for warrenty work. Thanks

 

Quadzilla makes a nice fueling box, and Smarty makes a nice fueling programmer.

 

Maybe i will go with thw Quad box as i already have the milage max, but isn't the milage max already the box i need ??
