Default gaps in acceleration

anybody else notice gaps in acceleration. i had a run in with a ricer on the highway today. some civic piece of crap. anyway i ripped him a new one, not once but twice. guess he thought the first beating was a fluke. i pulled off from him pretty good. this is the first time ive ever gotten my truck up near top speed. Lets just say i ran out of numbers on the tach(cleared 120). i noticed that around 105-115 acceleration was slow and then picked up strong again. myabe it was due to the rpms. might have been to low to turn much horsepower. I thought i saw a thread on this a while back but couldnt find it again. does the pcm starve the motor for fuel at these speeds? anybody else notice this?

Oops, I should have read this post before I posted my post... It is on the chugging too. Like cutting out, then back, then out then it finally accelerates?

doesnt do that. just doesnt pull as hard for a bit. i think it may have something to do with the gear ratio's in the tranny

not sure about 04 but my 06 the speed limiter hits at 170 km , or roughly 110 miles an hour maybe thats what you feel.

My first thought was the fuel mixture. I know that Chrysler (and probably many others) program the PCM to go rich at top end so that you won't burn anything up. Maybe this is what your feeling?

could be. Even still it suprised the hell out of me when it started pulling gain at about 115. Im guessing it tops out somwhere around 130. it cleared 120 and i called it quits. much to fast to be going in a truck.
