Over the weekend I had Flo Pro's 5 inch exhaust and the Mini Maxx installed. Deleted the dpf and the egr. The exhaust is straight thru. Big difference in the truck. On any other setting than stock the clutch starts slipping immediately.
You did warn me, but I needed a programer for the DPF delete so I thought I would get a good one. I can ride around in the stock mode for a while.
