Ver cool to see some real data on these, I appreciate your effort and it looks like a blast to be able to do. I am ifnorant in all things tuning and was curious what your thought is on the intake and stock tune seeming to get a slight jump on the power in both graphs.
Also I can’t quite see...
Just a heads up (wish I had looked for used on the steps before i bought new though I got 30% off) the hardware stays with the truck. Mine had it on from the factory so I just removed the bolts and reinstalled. Step boxes had no hardware.
Good luck!
