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?

RE: gaps in acceleration
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?

RE: gaps in acceleration
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.
