I have been reading about Torque Management on these trucks... but most everything i read is low speed, in town and doing burn outs and such ... so what about at highway speeds? I have a 2002 chevy RCSB and has the last 45,000 miles driven on the highway.. and Avg 420 per tank pretty well everytime... but not its getting 440+.. and today on the highway around 75-80 I backed it down from WFO to 60-70% and it made a stuble and possibly even a pop in the intake... makes me think its lean.. Truck had a whipple installed and yes all the whipple electronics intact... to me the truck has a "flat spot" between 35-70% throttle.. I did read and read before i made a post on this but might as well step up and ask ... KC

TQM comes to play mostly at low speeds and during shifts. The computer will pull timing down to -10 during a shift with all of the TQM installed. It will also ramp the timing up at a slow speed from a dig. Your flat spot may be a tuning thing if you have a stock tune. It could be running lean until it goes into PE mode, but that's all in the tuning. I know nothing and could only guess without seeing tuning or logs.

I'm gonna move this over to the tuning forum. I think you'll be better served there.
