Update TTI Stage 2+ with modified boost controller,
so far so good im seeing 22psi before intercooler and 19-20 psi after intercooler with 11.5-11.9 AFR.
boost peak around 3500 rpm(19-20 psi) and drop to 17-18 psi from 4200 rpm to redline...
i will dyno the car soon busy at the moment....
you’re quoting 300whp 300wtq. Best to get a dyno. The engine isn’t under full load until aroun 4K rpm unless your in 1st. So hitting 20 psi in 5th at 3k rpm going 35 mph is worthless at least in real world driving.....
I highly doubt your holding 17-18psi till 6000rpm. Only look at boost readings at exactly 5,800rpm or higher which will give you a better idea of WHP. In terms of torque try boosting in 1st or try boosting in 2nd at 3,500 rpm going 30mph.
I'd rather they put the 8AR in a Corolla. The "new" hatch is a great chassis (it is the old CT200h platform) and with the Focus RS/ST, EVO an Mazdaspeeds no longer being sold in the states (only turbo hot hatch is the CTR and that is way over priced) its a good segment to step into.
You know this is false, right? It is NOT the CT200h platform.
The new Corolla hatch is based on the new TGNA platform. The CT200h is a 2011 design which is based on the Scion TC.
I have noticed that my JB4 has 8 maps when I plug in the software. Terry only states that there is a +4/+5 (map 1 and 2) on his post in the N54 forum. Has anyone found out what the other maps correspond to? I wish the software would tell me what map setting is what. Only thing I can find is the list of bimmer maps.

For the Lexus production JB4 only Map 0 (JB4 disable) Map 1 (+4psi) and Map 2 (+5psi) are active.

No proven power gains between the 2 systems. The JB4 just allows you to connect to the OBD port for engine readings like AFR, boost, etc.
