Last i checked with BMS it was the same, but things might have changed since then.

I will check with them again and let you guys know

Confirmed by BMS, the G87 JB4 is different than the G80 & G82

The best thing about JB4 is Geo Smooth

Does anyone have a picture of the fuel pressure connection location for the jb4? As it's not documented in the install guide.

Installed JB4 on my car yesterday. Running Map 2 feels great.

RK front mount intakes, catless MAD downpipes, valetronic single mid, stock axle

Congrats, glad you like it

Would appreciate if anyone can answer, does JB4 connect to more sensors in comparison to the Racechip GTS and Dinantronics X? Is there any benefit if we are just running Map 1 or 2 on 91 octane fuel? Any comment on long term reliability with everything stock other than a non resonated exhaust?

Yes, the JB4 has more connections; the main benefit is the canbus connection exclusive to the Jb4.

Map 2 on 91 octane needs data logging, this can only be done with the JB4.

The biggest benefit of the Jb4 is reliability and safety; you are not blindly adding boost and hoping for the best. You can monitor how the car is handling the extra boost and more importantly, the jb4 can monitor it as well and revert to the stock map if things go south.
