It does have the boost pill like the 8/9. The boost pill restricts flow to the wastegate to help the ****ty stock solenoids get more boost. But the X also has 2 boost control solenoids, so you can get about a 24-25psi out of it with full exhaust, intake, and WGDC at 100%.
I would guess yes. My GF's MR with cat back, intake, tune (still stock O2 housing, down pipe and test pipe) was able to make 280whp SAE correction on a dynojet at 22psi. A test pipe, and O2 eliminator downpipe would probably get another 3psi of boost out of it, and 30whp. So 310whp. On a GSR, the lower drivetrain loss would result is ~7-10% higher numbers, probably 330-340whp.

I am still confused. So your ASP tune is virtually the same as the STU tune? How is that even possible if the restrictor pill is the one limiting boost and in STU you can't even touch the boost (not yet anyways)?
Maybe I am missing something in what you have posted?

He prepared the car for STU legally. He had the car tuned in an STU-legal manner (fuel/timing, boost table was untouched).
He then asked the tuner to make a second tune where the boost table was modified. This was the "ASP tune". Same hardware on the car, the only difference is that the stock boost table was allowed to be modified.

I'll have to take a picture to make sure I know what you're talking about...
Unrelated, January Solo fastrack?

at ECU "Clarification")
Cliff's notes of this proposal, as I interpret it: you can do a standalone. You can change boost (in the ECU).
I think this is bad for at least two big reasons:
1) Not selfish: $$$$$$$$ for real or perceived benefits of a standalone (buying one and paying someone to tune it)
1a) Probably a slightly less streetable, less normal car when you're done
1dos) generally not in the spirit of commonly available modifications
2) Selfish: this means the STis can change boost (because their hardware limit becomes the turbo) and the Evos basically can't (because the hardware limit is a boost pill which this proposal does not address).
I've posted this already on here, but this was my early 2012 STU tune vs an "ASP" tune done the same day on the same dyno:

So why the heck are we all running in ASP for.

Thanks. I was not questioning whether his car was legal in STU, but simply confused by the fact that a STU-tune and ASP tune can make virtually the same power. According to the chart posted above, he said the difference was only +1 whp.
So why the heck are we all running in ASP for.

I posted that dyno to illustrate that the new ECU proposal will not help the Evo 8/9 (I have zero knowledge of the X on this question) nearly as much as it will help the STi. IMHO the cars have pretty decent parity under the existing ruleset (at least relative to one another).
It will be interesting to see what the 2WD folks think about this.
Guess I will write a letter. No reason the Evo8/9 is the ugly duckling here if the proposal goes through.
Those numbers definitely aren't dynojet so hard to compare unless you dynod on the same machine. DJ, you can get 350-360whp. If I can get 330 with what I did, a few extra allowances and 95octane would get you that extra 20-30hp

Correct, that was on CBRD's Mustang/heartbreaker dyno. IIRC a normal stock Evo 9 does about 215-220 whp there with some rare ones reading higher.
