IS200t tune
I finally just ordered the BMS stage 1. Looking forward to the power gains.
Once TTI finishes their turbo modification, I am planning to sell the BMS and go with TTI stage 2 + downpipe + the modified turbo.
In the mean time, does anyone think it is worth it to add a down pipe to the BMS stage 1? Or should I just wait for TTI?

No problem. If you're near Taipei city then you're set!

Also some info about the tune & the process

Most welcome, well since Lexus is equipped with Denso ECU, they are famous for being "smart" in the sense that it will take few days to fully adapt to the new power to give you all the potential, I don't recommend removing and putting back process, but rather make sure after you drive the car switch to full ECO mode, which should be slow and unresponsive enough for the wifey

Another question, not trying to go full exhaust yet so does anyone recommend any axle backs? I'm liking that quad tip Apex-i 😍

For ~$400 I'd say it was definitely worth it. The stock tune on this car is absolutely horrid. BMS stage 1 makes the powerband much more useable. It's nice to actually feel something when you mash the pedal down, but the biggest difference is definitely in the mid range of the RPMs at 50%-75% throttle. That's where I notice the most improvement in terms of torque.

With the next TTI update for the Stage 2 we should be getting more hp and torque specially if we have supporting mods.
Stage 1- Is defaulted at +4PSI over stock.
JB4 system-
The JB4 is available both as stand along system and as an upgrade kit to the Stage1 tuner. It adds CANbus control and other features to the Stage1 tuning allowing multiple maps based on expanded engine criteria, smoother partial throttle performance, additional engine safety systems such as lean run or over boost, more advanced logging for those wanting to experience with different fuels and E85 mixtures, boost by gear to improve traction, and much more to come via free firmware updates.
While Stage1 installs in under 60 seconds the JB4 install requires an additional OBDII cable to run through an existing grommet in the firewall adding 15-20 minutes to the process.

JB4 Maps:
Map0 - JB4 disabled
Map1 - 4psi peak
Map2 - 5psi peak
Map3 - User Adjustable fixed boost map (similar to Stage1) where “boost safety”
setting on the user adjustment page determines boost added across the power band
Map4 - Stock boost with CANbus active for data logging
Map5 - 6psi peak
Map6 - User adjustable by RPM map using settings on user adjustment page. A
setting of 5.0 would request 5psi over stock at that specific engine speed.
Map7 - 7psi peak
