Ricoo, Is this the JB4 upgrade kit? I'm trying to figure out what will the kit do with the existing stage one piggyback Do they increase the horsepower and torque as well?

The install is pretty simple. Connects to the 2 boost sensors like the stage 1, but also has a OBD port connector that has to be wired to the interior through the firewall. The difference with the JB4 and Stage 1 other than getting engine readings are the maps.
Map 0- JB4 disabled
Map 1- +4 psi
Map 2- +5 psi
Map 3- user adjustable boost
Map 4- Stock tune w/ JB4 datalogging
Map 5- +6 psi
Map 6- Boost added by engine speed (RPM)
Map 7- +7 psi
Map 0- JB4 disabled
Map 1- +4 psi
Map 2- +5 psi
Map 3- user adjustable boost
Map 4- Stock tune w/ JB4 datalogging
Map 5- +6 psi
Map 6- Boost added by engine speed (RPM)
Map 7- +7 psi
@Rico, you got the JB4 upgrade. See the link posted below so you can install it.

After running the stock tune and then BMS for some time i was finally able to load my TTI Stage 2+ and the car is running like a champ. I am hoping to dyno my car again since the last results were done incorrectly. As you can see the run didn't start till later in the RPM range.

One question, does the new jb4 tune anything other than the boost sensors? The boost sensors will only do so much. There's a limit to what you can do in terms of manipulating the sensors. Regardless of if you're running +2 psi or 7+ psi the boost sensors will still only peak 1.5 psi in the lower rpm range and hold 1 psi on the high end. The difference in power between +7 psi is the same as +2 psi. At least this was my experience. It sounds like the jb4 upgrade only really provides data logging

When I tested the BMS we saw an increase in power at +4, +5 and +6psi. I do agree that less is more in some situations and we got the best performance at +5psi (230whp 280wtq) . At +6 we saw a higher peak torque but a lower peak power.

Where did you hook up your catch can?
What is the aftermarket heat exchanger with auxiliary pump?
