WOT issue? Can't tell if it's the tune or mechanical

So lately trying to tune my car, i'll do a second gear pull go to third and the car falls flat on its face, logs show it drops to waste gate pressure. it'll bog any time i try to go WOT again for about 2 minutes, from a dead stop like drag racing, this doesn't seem to happen. only doing a gear to gear pull like getting on the interstate or something.

One thing i have noticed, is that it seems to do it if i bring the car up to 9k+, but my load cells only go up to 8700 as I was on a stock head before, we left the rev limit at 8700, but if I change it, it'll bog. Would it do that if I go off the edge of the map? do I need to rescale my load cells to rev that high and retune?

Any insight tuners?

Try changing your break-points .... and then upload a copy of your current map.
