Has anyone talked to Tony and found out what his plans are yet? Being that a lot of us are running his tune already if he can match the results on top of the tti hybrid turbo he is working on, then the price may be cheaper for the ones that are already running the TTI tune.

Going by the data above the US specs are this:
335.1 PS to horsepower is---330.382883545575 hp
and newton meters torque is 451.8Nm to ft pounds is---333.2306ft-lb
So to Sum it up this upgrade puts down:
330 whp and 333.2 ft pound of torque. Great numbers for an upgraded turbo and tune.

Time to get in touch with them am on it
Last I heard from him is that they are doing Flow Testing
Great numbers indeed would radically improve the car's "Fun" Level :P

Only 15WHP with a 3.5PSI increase. Probably has a lot under the curve but this hybrid turbo is probably only capable of holding ~19PSI through the entire RPM range. The 24 PSI tune likely drops boost down to 19PSI starting around 4600RPM.
It being a no core works well for me but I will be holding out for a bit I think. I only just hit 3K miles on my 200t.
Any ETA on the JB4?

I am still testing the JB4 system. We don't have all OBD port readings as yet since Terry needs to fix that locally. Here are a couple of datalogs that i did. For some reason the BMS reads a lower boost, but still good enough to compare.
This log was from the stacked tune (TTi Stage 2+ & JB4 +4 PSI) ignore pedal and throttle readings on the log since it was fixed via firmware update.
Stock ECU tune with JB4 set at +5PSI until 4000rpm +6 PSI

With no added boost and stock ECU tune i saw a peak of 11.2 PSI.
ECU PSI- is the "fake" boost reading that BMS is sending back to the ECU (reason why F Sport boost gauge reads low)
Target- being the "+" boost value that the BMS is creating
Boost- is the actual boost reading from the sensor
As you can see with the re-flash plus JB4 +4 PSI we saw a peak reading of 16.6 PSI. With the JB4 and stock ECU tune theres a peak of 14.6 PSI. The stock turbo is still peaking at low rpm and dies out up top.

The JB4 is still reading the boost incorrectly but for what it is doing it's fine. The interesting thing is the pedal to throttle part of the info on there.
edit: disregard the throttle part just read your edit.
All things considered the turbo can hold 1.1bar all the way to redline that is impressive seeing how small this turbo really is.
Any ETA for JB4 general availability? Does Terry need another tester?

I noticed this too. This modified turbo is capable of plenty of boost. The 24 psi tune is quoting whp, not torque, so the 24psi tune isn't building and dropping to 19.5psi. It rather builds up to 24 psi through the entire rpm range and holds 24 psi at the end resulting in 345HP (I'm curious of the wtq). I think the reason we aren't seeing much gain past 335whp is because the injectors and/or fuel system is running out of steam, it could be many different things but I would narrow it down to the fuel system
#3029
Considering the 19.5 PSI is the only thing we have dyno info on in the for of 335PS @5400RPM that indicates torque drop off indicative of flow running out. Only 15 more wheel HP with 4.5-5 more PSI indicates the torque drop off is even more drastic with the high boost tune. Like it or not the images shown are not a substantial increase in turbine inducer size (TTI's hybrid looks to be larger and its not really that big). If our stock setup can only max boost pressure at redline to 16PSI I would estimate this hybrid is 19-20PSI max at our redline though 24-27PSI peaks are definitely realistic. like i said i would bet the 24PSI tune has a lot more under the curve than the 19.5PSI tune, but peak HP will not increase that much because the turbo is probably falling off before 4800RPM's still.

JRC’s modified turbo; clearly has a bigger compressor wheel.
TTi’s modified turbo.
I have a feeling that tti will still hit the same 330whp but I think the JRC turbo has much more room for power. I wonder how they will compare in terms of pricing
