On my 15 and some customers LML's I have tuned. If I stand on it it will go well up over 120 but if I let off it has no power still it get back below 75-80. I know this has something to do with the switches but have yet to come up with the right combo for this one issue yet. any help. I have the fuel tables set to 0 for the speed limiter also.

I'm not sure if the 2500/3500s are the same, but on the 14 and newer 1500s the speed limiter is controlled by the BCM unless it's set to ECM in the ECM tune.

Bumping this thread to see what others have figured out, the 15.5 im messing with is doing the same as Lee's but I can run this one up to 90 let off and it will not pick power back up unless I drop speed below 55mph, maybe a switch combo along with some changes in the speedo limiter parameters will do the trick? I see the 15.5s have misc parameters so maybe raising those numbers along with the PTO, Can Bus speed limits hopefully fixes the issue, if anyone could chime in i would sure appreciate it! Thanks
