I had some free time today and did a few more 3rd gear pulls. Torque at 3k was nearly identical to the pulls during the tune, but today torque was peaking a little higher (but at a similar RPM).
The HP also held on a lot better on the high end (climbing all the way to redline). The higher RPM HP peak makes more sense. Not sure why the other pull started dropping so soon.
Baseline:
Peak HP at RPM: 239hp@6,000rpm
Peak Torque at RPM: 259lbft@3,200rpm
Stage 1:
Peak HP at RPM: 251hp@6,000rpm
Peak Torque at RPM: 294lbft@3,400rpm
Stage 2 (during tune):
Peak HP at RPM: 275hp@5,600rpm
Peak Torque at RPM: 316lbft@3,400rpm
Stage 2 (12/24 pull):
Peak HP at RPM: 298hp@6,100rpm
Peak Torque at RPM: 342lbft@3,500rpm

Yesterday I installed the IPR TMIC and Forge BPV. Both are painted black. The Forge BPV that I got will not work wit the stock TMIC, but works fine with the IPR TMIC, see the photos for more details. It is very similar in size and shape to the stock unit, but it is all metal. It comes with 3 springs (only 2 seen in photo, because 1 is installed) and 2 shims for adjustment (for correct boost range).
The BPV is obviously a very easy install. I did add hose clamps to both connections for added security (see photo in next post). I still using the stock intake system and I can only barely hear the valve when it activates (I couldn't really hear the stock on at all). But I do hear it vent when I shift under boost, so I know it is working. Not much of a "clink" sound (that I've heard is common with the Forge BPV), but that may be more audible with an aftermarket intake.
Forge BPV:
Stock BPV vs. Forge BPV. Make sure both hose connections are pointing in approx the same direction as the stock BPV or it will be difficult to install.
Note the different seal shape between the stock BPV and the Forge BPV.
The Forge BPV will not seal on the stock TMIC. But it will work with the IPR TMIC (or just about any other aftermarket TMIC).
The IPR TMIC is a pretty beefy unit and feels very solid. The all-metal construction looks like it will hold up much better than the stock TMIC. It was a very tight fit, but once I got it in there weren't any clearance issues. Took quiet a bit longer to wrestle it into place than the stock TMIC, but it does fit and all the bolts line up. Just don't tighten any of them fully until you have them all started. I like the look of the black TMIC in the engine bay 
Stock TMIC vs. IPR TMIC
The IPR TMIC only has a slightly larger footprint than the stock TMIC, but it is much thicker.

Today I installed the Defi Red Racer boost gauge. Right now it is in a temporary mounting location until I get my gauge pod in. The install went better than I expected. I went through the fender with the wiring and it was actually really easy (after I took off the wheel and opened up the fender liner). Much easier than getting through the firewall on other cars I've worked on. Here is a link to the photo's explaining where I went through:

Once I got it all hooked up everything works great. Sits right at 0 with the car off, and then goes to about 20.5 inHg at idle. Hitting peak boost at just under 20psi. Same that I have seen while logging. The color of the gauge matches perfectly.
The gauge does the sweep when the key gets to the ACC position, but then when I start the car it turns back off for a second and does another sweep. I think I must be tapped into the wrong fuse. Any suggestions?
