thanks for the feed back and after reading the response I see i could have more clearly defined the issue while what i wrote was correct what i failed to add was the even when the the cruise was not engaged the engine brake does not seem to have much effect in either low/med/high. however i need to try and shut the cruise power off as Bob86ZZ4 mentioned above this may work. However the manual i have talks about the engine brake working with the cruise so i'm a little confused. Will need to talk with freightliner service center to see if they can program the brake to work a little better. thanks again for the info
