Hey wicked. Just a thought for you to maybe change in the first post.
As far as the exhaust goes, I would suggest having at least a full 2.5" catback with a 3" dp. Reason being is because your EGT's can climb really high really fast. And if you're one to hot lap your car at the track, your motor could go boom due to high EGT's. Other than that, I don't have anything to add to it.
Good post btw. TVS ftw!

Just some info for people. Tuned my car yesterday...mods r in my sig...tune info is the following
AFR = 11.9
Timing = 25*
KR = 0 (didnt even see any at all during the tune process)
IAT2 = 149* after 4 pulls on the highway in 27*C weather
Boost = 20psi
1st gear = idle - 4000rpm reduced to 75% boost, 4000-5000rpm starts to climb, by 5000rpm it makes 100% boost. All other gears are 100%
Trim = 0.8%
Car pulls like a **** :P

What about fuel system. Would I need to do a return line, or just upgrade to 79lb'ers to run a 2.75" on my 2.2. Would my current 60lbers be enough fuel?

That boost level he's on the factory 80mm pulley. ~3.1 or equal to the factory pulley on the M62.
I've got the same set-up. My tune is a little different. 11.6-11.8 AFR, 22* of timing and 50/50 meth mix for the moment. Going to bump up timing this weekend and up my meth content.

Is it the colder the temps the 'richer' your tune should be and when it's hot the 'leaner' your tune can be? I really have no idea, just taking a blind stab at it.

Alright, so 79lb'ers it is. I don't want to go with anything larger then a 2.9 but 2.75 is my goal. How has our stock fuel pumps held up to the 79lb injectors? I know a few are running them but cant remember if they had an additional inline or aftermarket in-tank.

So with a 2.5" pulley and 8K redline wont be a problem for the TVS to handle? This is of course on a motor build to handle horsepower oviously not on a stock motor. I'd like to build big horsepower on a supercharger rather than a turbo just because I think it be unique and different. Is it possible to see 30 PSI on a TVS is what I'm asking more or less?
Also what mods would I need to do to my car to directly bolt on a TVS right now running the stock TVS pulley which from what i read is a 3.1" pulley. My guess is bigger fuel injectors, the LS4 TB and 3" intake, my exhaust system is completely opened up so I know I'm ok there and tuning inst a problem. Is a H/E a must, should I get one before I even buy the TVS?

First thing.
You don't want the 2.5" pulley.
I ran it just fine on stock motor 28 psi at 7400 rpms.
The 2.75" is the smallest size that will allow you to run optimal timing.
Right now you could strap the tv on to your car and drive just fine. A 3" intake is not necessary but is nice to have becuase is slows down your maf freq.
If you wanna chat i can pm you my phone number.
