Default turbo pressures?

Can someone post some of their logs for a stock tiptronic? My AWE vent boost gauge showed up after 3 months of waiting and I'd like to compare some boost graphs to make sure my car is proper - thanks

Are you running a chip?

I think you're going about this the wrong way. With chip modding your first concern is going to be boost leaks, either existing ones that are made more noticeable or new ones created by components failing under higher pressure levels.

Reading the boost gauge is really only going to tell you what the turbos are making, not if the system is properly sealed (too inaccurate for that IMO). If you have a serious boost leak you would know it already.

The new chip is going to make the turbos make more boost - that's when the gauge will come in handy. Chip it first and then check to make sure you're hitting the boost levels the chip is advertising. Should be around 17-20psi chipped.
