E450 W/Cruise on - downhill downshifting - aggravating !!

Sometimes the engine will hit 4K or 5K RPM ... can't be good !!
QUESTION: Is there any way to prevent this (other than not using cruise control or turning it off on downhills) ?? Maybe one of those Bully Dog engine tuners ??
Anyone else have this aggravation ??

yes i have that same problem and its aggravating. my 98 gm powered mh didn't do it, and i would like to change this one. if i wanted to brake the mh going down a hill i can do it with the shift lever, but when in cruise , i like to accelorate down the hill to get momentum for the next hill, but the stupid cruise setup wants to brake you.

I also have an E450. Call 5star tuning. Their tuner is the best thing you can do to make your rig much more drivable in all situations. I really like mine. WOW is the only way to describe it.

You two please let me know when you plan to drive through Colorado's mountains, So I may be safely off the road when you do.
