BiggBoy will become famous soon enough
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?

Not sure how it ties to your oil change, but it sounds like your running out of fuel/pressure. I know alot of people have been switching to the aeromotive pumps for boosted applications, you might be on that threshold.......then again I could be completley wrong.

I would send some live feed from your tuner to hemifever and make sure everything is where it needs to be as far as tune and numbers and then go from there.

The oil change part stubbles me also. I could dump a little more fuel into the motor via my trinity I guess. I can't see how a mostly stock NA motor can pull that much.

interesting..I was hoppin onto the freeway today and decided just to go 3/4 throttle instead of wot...and if I didn't know any better, it almost felt stronger... but when you think about it, you need to give a wot datalog that includes a/f logging to your tuner (unless your tuning on a dyno)...my tuner is always harpin on me to get him some form of a/f logging in open loop (wot)
