That's weird, have you every experienced the boost fluctuation issue due to the faulty vacuum regulator? I had to change mine around 12000 miles and so far it has been working fine.
You can upgrade from stage 1-2 easily. The re flash would give you the most power gains and is reversible with the tools, but it is a bit more complex than the simple piggyback system. Do some more research to find out what kind of power you are looking for, some may say that its not worth to upgrade an IS200t, but i beg to differ.![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)

Tony and I were chatting earlier this week about your issue. I really want to believe that with the recovery the ECU was reset to"new" and is limiting the boost pressure for the breaking in process. I would say put some miles on it and see how it goes.

Highly doubt that, I have reflashed my Evo over 100 times and it never had these issues and in the Evo reflashing replaces the whole ECU software meaning that it is like "new" everytime

Oh ok, it's a Toyota though so never know lol. Hopefully he can find the issue soon, their stage 2 IS in Taiwan is running fine. Once I get my down pipe I will eventually upgrade to stage 2, so let's see how it reacts on my car.

It will be fine on urs thats for sure...am starting to believe that it is more of a software version issue that is different than US and Taiwan, or else it can be a solenoid issue though an getting boost when we are changing the map but it is not consistent and what complicates things is that it is not fluctuating nor dropping which makes the solenoid looks like it is working fine

well it differently is much better since its more lean and more timing is involved plus the slightly added boost but the boost is not holding if u notice, thats one of the reasons i asked u for that video wanted to see how urs is holding and reacting between shifts

I really like the sound of your car! Is it a straight pipe cat back? I want to see you guys do a 0-60 while brake boost launching at 2k rpms. It allows the turbo to spool up but you might wanna let some air out of your tires, that way you wont just be spinning the whole time
