EVO 9 20G-LT + GSC S1 cams dyno!
I think the gains are pretty nice, peak gains was close to 30whp, but some areas in the power band you were seeing gains close to 50whp.
A couple things I should mention though-
Tuning Technologies does not have a very high reading dyno jet, and is located 1,000 feet+ in elevation.
You dynoed on 91 octane and you have a high flow cat (not a test pipe). Both of those things are taking away some horsepower.
I think the 20G-LT is a great turbo, but honestly I wouldn't expect to see as big of gain in power as a EVO VIII would see with the 20G-LT. The stock EVO IX turbo can hold 23-24PSI on pump gas.
Swap the HFC for a Test Pipe, get a 100 octane tune, and run 26psi, and your numbers would be like 380whp+ in my opinion.

Thanx for the positive comment guys. 
I am running the Burschur high flow cat and the boost was set at 23psi. The blue curve was also set at 23psi with pretty much all the bolts on without the turbo and cams.
I'm thinking about swaping out the cams and see what the turbo can do without the S1 cams. What do you guys think? Maybe the cams need a bigger profile, because during the tuning at 16lbs, the car made 324whp. It just seem adding 7lbs the car hit 355 and thats it. Maybe going 272/272 cosworth cams are a better idea?

i would not worry about cams i would get race gas or water/injection,it's the gas that is killing you i made a little more power the you on my evo 8 with less mods it's the gas!i have crappy hks 264/272 from what i hear these cams are not aggresive at all!

I'm still on stock IC, yes so im thinking about swapign out the S1 cams back to stock and hitting the dyno again. If i figurer out its the turbo then im going with a GT turbo series. We just cant believe how adding 7lbs only give us 25whp. i'm starting to believe that the S1 cams might have something to do with it.

yeah,
thats pretty weak on a DJ, even on a low reading dyno really....
hmmm
id be curious to see a cosworth gsc back to back cam test....
well, i do need to break in my new dyno hee he

Thanx for all the positive comments 3000ways. I just want to hit 400whp on pump for my daily. Just fustraded that im only 40whp and it just seem like I have to run menthonal injection just to do it.
Are you sure about that (swapping the GSC S1 Cams for Cosworth)? A couple of threads below the one you posted, a EVO IX with very similiar modifications as you (minus the 20G-LT) put down 337whp/340wtq. You made 18whp more on 91 octane compared to his 93 octane, but of course you have the 20G-LT turbo compared to his stock turbo. I hate comparing dynos, because so many dynos read differently (Al's DD reads like a dyno jet), but my point is your numbers are fine and I hope you don't waist money when you don't have to. On Tuning Technologies dyno jet, 355whp is very strong, don't get caught up in comparing your numbers to others, it will just leave you confused and with less money. If you truly think your EVO is underachieving in power, then get rid of that HFC, and get a test pipe, and get tuned for more boost and run 100 octane. I'm sure the 20G-LT should still be efficient at 24-25PSI, especially with 100 octane gas. Then you can have a very nice dyno sheet to show to your friends and impress them with.
Having run on the TT dyno using straight 91 on my 3076 kit (and getting 350/330 with 264 cams), and now having the FPGreen turbo on for a while, I'd say your numbers are right in line with my expectations. Frankly, you're not going to see 400whp on that dyno using straight 91 and that turbo. Period. Given that you've got the best stock-appearing bolt-on turbo on the planet, it's safe to say that if you found a turbo to give you 400whp on 91, it would be significantly laggier and not nearly as much fun to drive. Look at it this way, you're hitting the same peak power as my 3076 kit did using the same fuel, and you've got none of the lag. Cheer up! The fuel here is the largest hinderance to big whp numbers. It doesn't look to me as if there's anything wrong with your car. I would expect mine to perform similarly.
take it to the track and see what it traps...
but just from the baseline to what its doing now.. 25-30whp is a crock of poo...
for 2k
i would jsut get a 35 shot of nitrous for 400$ lol
