Question Running Lean

Okay guys, I'm cruising @ 70mph, let off the throttle(coasting) and the wideband goes lean. But while doing so the truck jerks like as if its starving for fuel. If I just barely touch the throttle, it stops jerking. Would the the throttle cracker, follower or idle running air flow take care of this?? I know that fuel needs to be taken away when letting off the throttle but i shouldn't do this. It just started doing this a few moths ago. Also it gets worse when going down a hill.

Thanks

James

I would just turn it off completely at first to make sure that is it...then if it is you can play with the entry and exit settings

The hold time is 0.000, entry ramp rate is 0.050 and the exit ramp rate is 0.013

Just set the enable temp to 250 or something higher than you will reach.

Whats funny is that the above stated values are in the stock 6.0 and LS2 tunes I have but theyre zeroed out in all of the stock 5.3 tunes. I'm gonna zero them out and see if that fixes/helps the problem.
