Default WOT power lose.

I have a slightly modded truck

ARH headers, S&B intake, 87mm TB, and full custom exhaust.

Right now I'm running a hemifever custom tune. I love the tune, pulls much harder then running a canned tuned. But I have a problem with both tunes.

When I'm a WOT It seems to bog down a little in the 2500-4000rpm range. If I let off it a little while its bogging down. It will take off like a bat out of hell.

Other thing I noticed is that right after I get my oil changed the bogging stops for about 500 miles (my 0-60 times on my trinity confirm its true.)

I took it to one shop, and they are convinced they could fix my problem with there $800 dyne tune...

I might throw a AF gauge in to see if it pulls rich or lean in when this is happening.

Any ideas what it could be?
