Default 2008 H2 Second gear bog down with intake noise

Do you 08' H2 guys notice the second gear bog down with a lot of intake noise? In other words on the 1-2 shift it bogs, kinda like a big underpowered boat trying to get on plane, with a lot of intake noise. this is my second 08' and both of them had it, the second one being a little better than the first. It's not as apparent when starting from a dead stop and running through the gears with moderate throttle. It happens mostly when trying to accelerate from 2, say when you pull up to a light and then it changes, or when going around a turn and the trans does not downshift to 1 Maybe this is due to a gear ratio change? If i shift it electronically and wind up the RPM's it seems a lot better.
