mechanicals aside, no one to my knowledge has been able to crack the USDM ECU code and thus tune the USDM ECU, though there have been a few false claims of being able to do so. toyota has "the key" to the 2is ECU, and i've heard from a reliable source (names withheld for anonymity purposes) that even TRD has been unable to get their hands on the code.
as such, all possibilities of forced induction or stroker kits will still be handcuffed by the 2is ECU at the upper limit. not that it's not worth trying, but without being able to tune the 2is ECU you won't be able to reach that level of maximum power output.

As I keep pointing out, the ECU has nothing to do with this.
TOMs in Japan tunes the JDM ECU. And still doesn't recommend running more than 6 lbs of boost on gasoline without risking the engine. (and that's on 95 US octane fuel too)- that's straight from the mouth of a guy with the TOMs kit on his 350 who spoke to them about upping the boost).
I believe Lobuxracer actually ran the math and found 7 psi would be the absolute limit of the motor. The ECU can't lower the physical compression ratio of the engine after all, no matter how much ECU access you've got.

Kurtz, i agree with you 100%, that the ECU will not allow for more boost, compression, etc. simply put, it can't change anything physical and/or mechanical.
however, one of the things the ECU does control is the fuel injection system, and without having access to that, running at the upper limits without enough fuel or changing the air/fuel ratio to maximize the power given the physical/mechanical limitations means a lower of safety/error margin.

Amount of psi aside, I think we're missing the big picture. Assuming Brian's venture is successful, we'll have an option to provide boost to our cars. This sure beats the current option for USDM vehicles, which is zilch (unless you want to custom build your own).

as such, i made the statement "mechanics aside".

You might manage a tiny bit of extra power tweaking the F/A mixture, but what some folks have done with SAFCs suggest it won't be more than 7-10 horsepower... hardly worth the amount of effort breaking through toyotas encryption would involve.
The fact that even WITH ECU access TOMs only makes more than 10 hp than LMS did without ECU access supports exactly that view.

I'd rather have a company R&D some quality internals vs. going the redneck barnyard route. I don't ever see big FI options happening for the IS though - it's just too factory high strung that the budget for any real undertaking is monstrous. That and no big name tuners are jumping onboard. Guess we'll just have to stick to "which LED should I run in my DRL" threads. Sorry guys. I'd love to be wrong, but...

Enough is enough! So, I had the Twin Turbo kit on my car and then some people blew up with sales because I marketed the crap out of it and it worked. Now, I hear that people are getting screwed and that just ISN'T RIGHT! I ended up getting screwed also because now I can't turbo my IS C for SEMA. Well, that is what others think anyway 
So, I was talking to my boy Javed with the IS250 and we are going to develop a SuperCharger WORKING system next week. I have EVERY connection known to man and I don't BS or play games, I get stuff DONE!
I went to the other company and said I want a forced induction kit for IS250/IS350 owners with 6psi, intercooled for under 6 grand. Well, I'm going to acheive that gosh darnit ourselves at enthusiasts. It is a LEXUS and we want to make some power. I ordered my ProCharger C-2 unit TODAY and will have in my hand on Wednesday. I should have pictures, video of this by next weekend!! This isn't rocket science guys, enough is enough!
