    What are the suggested tweaks to a 435 5ek to make it run well without changing hard parts?

    Did the injector codes impact your mileage?

    Not trying to start an argument but i have 900L with muffler under the bunk, I bought a free flow muffler to replace it and since my truck had big air compressor and four air tanks from the factory it would not fit, so i hook it up straight, (for one day, to loud for me), couldn't feel any power increase down low and felt like it lost power above 1600. I put my old muffler back on for now. any thoughts on this one.

    Good one Rockhauler!! Seems that the ASCERT's are more air hungry than the "E's". Wondering ifthe excessive sound might have been coloring your power feelings? Wondering what the pipe fron Pitts. Power would do? Jus' throwin' ideas.

    Hello Rockhauler-

    Maybe without some backpressure, turbo taking longer to spool up?
