    So, I had to take my wife into town so she could pick up her truck today, and on the way home tonight.....

    I'm in my '07 4x4 RCSB SC 5.7(TRD/Maggie w/TRD tune) completely stock except for blower and fit kit, just turned 189,000 miles..
    My wife is in her '16 ram 2500 w/6.7l Cummins and 6speed manual, straight pipe, def delete, some kinda tuner and a bunch of other shit, 110,000 miles.

    We're basically in the middle of nowhere, nobody else on the four lane highway, I'm tired of being behind that black lung POS, so I get in the left lane , pull up beside her and she tries to not let me around.lol
    I pushed the go pedal and proceeded to finish what I started, and when I was getting up there in speed ,it was kinda like the ECU was cutting power.
    My truck pulled hard and no knocking, no pinging, no CEL, I wasn't quite WOT.
    My question is,
    I thought the TRD tune turned off the speed limiter?
    Could I have been having some belt slippage?

    TRD tune doesn’t turn off the speed governor. Bullydog does plus it gains 90hp and 50tq to the rear wheels over whatcha got;)

    Thank you for the links, I'll check them out.
    The TRD tune had to at least bump up the speed limiter? because I was over the last number on the speedo still had a little bit of pedal left, just didn't seem to have any pull left when I pushed it to wot.

    And if that's true what you said about the BD tuner, 90hp&50tq, Holy shit Batman!!
    What a fuckin Beast!
    I was talking with a local tuner that just got HPtuners. Unfortunately @ViktorG stopped doing remote tunes because I wanted to try his tune.
    Sounds like a BD might jump to the top of the want list.

    The TRD SC tune has the speed limiter set at right around 120-125 mph

    Thank you Viktor. thats what I was feeling in my accelerator was the ECM pulling power, Damit!
    Looks like I'll be getting a BD unless you start selling remote tunes again?:fingerscrossed::spending:
    Did your tune remove the speed limiter?
