Hello, new to the forum and new to the powerstroke/diesel truck thing. I have a 2008 6.4 FX4 I plan on lifting 6" with 20X14 AF Blades w/ Toyo OC 35/12.50X20. It already has the ### and *** ******. Along the frame rail there are 3 plugs total, 2 of which look like o2 sensors that are just tucked away with the sensors still attached the other one (furthest to the rear) has some kind of resistor plugged into it. The truck runs amazing as it is but of course I want it faster but not extreme. What would be a good basic tuner that would give me good improvement without having to ****** the other valve on the engine? Is it necessary to ****** the ###valve when adding a tuner and what are the benefits of the ******? And yes, I know how to use Google and know how to use the forum search as well but as we all know, searching can get you just as confused as I may already be. Just looking for some input from guys with experience.
