:help: Hello Gang.
NewBe Here I have a 05 Chev.2500HD DA CC, SB now have 1800 miles on it, it will get up and go from 0 to 90 right now but from 95 to 100 it seems to take for ever. is this the norm. The first Diesel for me.

probably hitting the limiter right there. im not sure where that kicks in though. if it gets up and goes to that point im sure there is nothing wrong with the truck

First off, welcome... Second, no reason to go that fast unless you are on the track..LOL
I would say that you are hitting the speed limiter, usually shuts them down somewhere around 96-98 mph depending on tire size, so if you are stock then that would be the case....
