I otice when creeping & crawling in traffic (I let the truck idel in drive) that I have a minor surge, 50-75 RPM, as it goes. It is actually a little larger right after I accelerate a little (because the gap widened) and then go back to idle. This may just be the computer doing its hysterisis thing but I would have thought that would be faster.

Sound like anything anyone else has noticed? I have a Gen 1 2001 SuperCrew with the 5.4L. Only mods are K&N & Superchip.
