Hello everyone. I just wanted to post to ask if there are any things I need to do that will benefit the engine, tranny, etc. on a routine basis. The truck is a King Ranch with FX4 package with 137k miles and is, as far as I can tell, in excellent shape.

Are the mods worth the payback ? I mean I see the cost of some of these to get them to 20mpg and more hp, but how long does it take so actually get the return on investment from these ? Also, are the consequenses on the engine worth the improvements ? I am just askng because I am new to the powerstroke and really could use any advice.

Thanks

I saw an increase in mileage when using an SCT tuner. That will only happen though if you can keep your foot out of the inter-cooler.

i wouldnt tune it until you address the weak points of the engine.

EGR Delete, Exhaust, And a SCT programmer with custom tunes. Just go mild on the tunes till you can get some studs on the enging and a good set of gauges so you can detect a problem asap. Good Luck and WELCOME to PSO
