Did you REALLY notice a difference? Ive heard yes and no... I didnt really feel much. So other then eliminating the heat from the TB (and making it easier to work on) i dont see how it does much. Ls's were ment to run 200-210+ degrees, my turbo car doesnt even see 190 degrees w/ the coolant going through the TB.

I noticed a slight improvement in throttle response...nothing major...
living in florida I probably noticed it more than others....and with you in vegas...im sure you would notice a slight throttle response increase...
Cant hurt right?

I did the coolant bypass on mine. The TB was lava hot to the touch before... so great for horsepower...
Basically I just took the hose that runs from the radiator and put it directly to the head. It doesnt interfere with anything, and it doesnt require spending money.

ive only capped the TB on my turbo car because i creates vacuum... which throws off the turbo.
Its part of the PCV system... If you are going to remove the line, it needs to be capped (on the TB) because it would be unmetered air getting into your TB, your car would run like crap. Thats where your getting oil from probably. You could put a catch can on it... you just splice the line attach the can in the middle and your done, while keeping the 'stock' PCV system.
Or cap the TB and put a filter on the end of the line, it needs to stay open because it relieves pressure from the crank case. Thats how my turbo car is.

Hey CTS-V guys. I was just reading this and I thought that I would link you to a catch can install from LS1/2 GTO. You can also make your own using an air compressor filter and some hose and a mounting bracket. I also agree with the seafoam for intake cleaning.
The directions say to run it through your brake booster vacuumn line but we all induce 1/3 can ever so slowly into the vac port just behind the tb. I pour 1/3 of a can into a bottle that has a flip up nozzle and put a 1' hose on port's shaft. I then just put the other end of the hose over the bottle and the vacuum will suck it out. It is emphasized to induce it slowly so pull the hose off of the bottle occassionally. When done, shut the car off and let it sit for a while. Here's the fun part and If you have any close neighbors, you should've pre warned them because if they see the smoke, they just might call the fire co. Start it up and watch. The more oil you have in your intake - the more smoke you'll have.

Not uncommon at all. Mine looked way worse than that last time I had the inlet tube off.
What you're pointing to here is the Vacuum port.
This is the vent. It lets clean air pass through the crankcase, to prevent too much vacuum. 
As stated above its the coolant passage.
This is all you need to do to bypass that, if you so choose. Just connect reroute the hose that runs from the "T" above the radiator to the passenger side of the TB directly to the coolant crossover pipe that connects to the head. and throw the short piece of hose away.
