over revving problem

I have been trying to figure this out and really getting tired of the problem. So if I rev my truck to 3k rpm it will have a slight surge and rev to like 3600 rpm then when I let off it will come down a few hundred rpms then rev itself again up slightly for a split second then finally come down. If I rev it up to then same 3k rpm let off then hit the pedal again to stumbles then revs up fine. This issue only happens around 3-3200 rpm, before or after the truck runs normal. It doesn't matter if I'm on stock or extreme tune. There is no response from the throttle pedal for the first inch of pushing it down but people say when it goes bad it won't work at all. And since I put on my s&b cold air intake if I get into a hill and throttle it at a lower rpm lets say 12-1400 rpm it will start to turbo fart after about 15seconds of pulling. The rev thing has always done this even when I bought the truck used and bone stock, the turbo fart has only been since the cold air intake.truck builds plenty of boost with little turbo lag. Near I can guess maybe two issues... sticky vanes and some other sensor iguess. This is on a 07 6.0. I have an egr delete, arp studs, ccv reroute, airdog2 with sump, cfm large mouth intake, s&b cold air intake, edge cs juice with attitude with 140 horse tune and running the atlas 80 ficm tune. The revving issue has been going on from before all these mods.

4 inch down pipe 5 inch stacks no cat, Powermax turbo, CFM large mouth intake elbow with larger pipe, S&B cold air intake, Edge juice with attitude CS with custom PHP tune. Atlas 80 ficm tune. Airdog2, TRP sump, 6.4 banjo bolts, Blue spring, Zoodad mod, Traction bars, counter sunk tool box molded around my stacks made by me, Coolant filter, ARP head studs, southbend duel friction clutch, complete EGR delete, DP mod, high idle mod, CCV relocation, 35 inch fierce attitude tires on 17" helo wheels

You have probably read that some poster have a somewhat dead pedal, and others have instant response. You should not have 1" of dead pedal. It is quite possible the internals of the APS are causing your problem. If they all move in unison, it will not throw a code or go into protection mode. I don't know if the Edge you have can grab the PID for the APS, but if it doesn't, it is possible to test the pedal with a digital meter. I can't remember which pins are mates or the 5v source, but a quick search or wiring diagram will tell you. The pedal (APS) is not very expensive, but they don't fail very often either. You could probably get a spare from a junk-yard to try it. This pedal is used on a large number of ford vehicles, so you don't need to find a diesel truck to get one.

If your IPR was a bit sticky you could get similar results.

With a stock system your turbo shouldn't be blowing back, unless your EGTs are high and your vanes are closed. FWIW, under load, your TC should not be lock at low RPM, your best torque is about 2400 rpm. If you force the downshift to put the power where it needs to be, 2000 rpm or higher, your truck will be much happier with no farting.
