Anyone mind reviewing this tune?

I'm new to tuning, but picking it up quick. I recently swapped an LS6 cammed LQ4 (6.0L) into my 2004 Yukon. It has a K&N CAI, and gutted cats. This replaced the worn out 5.3L. I had a local shop tune it, and we found out that my IDC was over 100% at 5000rpm. I upgraded to the 8.1L injectors today because they were a direct swap, and 42lb instead of the stock 24lb. The shop retuned it, and was able to get a lot closer. I am having an off-idle stumble problem. Anyone mind looking over this tune and making recommendations?

Post a data log of the stumble.

OK, here is a log of a quick drive around the neighborhood. I stopped to let it idle for a few seconds a couple of times so that you could see what was going on when I tipped into the throttle. This is only happening between 1200-1600rpm under light throttle, light load conditions. If it was carbureted, I might say it had an accelerator pump issue - that's kind of what it reminds me of. If I tip into the throttle more quickly, it doesn't happen.

2004 Yukon, 2WD, New LQ4 (6.0L, 60K miles), LS6 cam, K&N FIPK, gutted cats. Brand new MSD wires and NGK plugs gapped at .041.

BTW, it made 330/374 on the local dynojet yesterday with 32" tall Kuhmo mud and snow tires on it.
