    RaceME Ultra Help!

    Hey everyone, I need some help here.

    I was going to call Canada Monday, but I wanted to see if someone here had experience with the same issue.

    I went with Ultra tuner (I figure it was cheaper/easier for now and would upgrade to Warp when I do VB for trans) because I got the 5mph service DEF warning.Did not want to repair factory system and then be left stuck on a road trip.

    Tuner installed without a problem, battery charger on for days prior and during install.Used 3.5" carbide hole saw easy for deep cleaning of DPF. Note truck ran great even with service DEF warning 5mph max speed in 150 miles.Truck needed Doser valve, but tuner cleared the warning.

    I installed the tuner before it reached 5mph max speed mode, still had 60 miles to go before lockout.

    I installed 200hp,1900rp, 29°, quick spool to see what this could do, and I figured I would back it down the next day.

    The truck was a smoky mess, with no power at all, even cruising at partial throttle billowed black smoke worse than my 9612v lugging 5th.

    I figured, ok, maybe 200 is meant for aftermarket turbo or other mods.

    I pulled over and installed 30hp with defaults; the same thing was terrible(low power,smoky).

    I installed 120 default everything, which seemed a lot better, but only has power between 30mph and 50mph, and the truck feels like it is restricted.

    I can not get over 70ish on the highway, and throttle input does nothing past 1\4 throttle at that speed. Like my pedal is dead past half throttle maybe.

    Air filter clean, fuel filters not old again truck ran awesome before the tune.

    I am hoping it is the ECM relearning?

    Maybe EGR stuck open as I have no clue about these trucks, my other truck I have had since 12' is a 96 12v 5sp dually. I could do all the work on that myself with my friends and I hope this truck is the same.

    Thanks to anyone that can help me.

    P.S. My turbo is only showing 1-4lbs of boost on dash now, I do not see any leaks, and my EB seems weaker though the gauge for that works.
