Can I read the Turbo's boost level via the OBD2 port on a 2015 Sonata 2.0t?

Well the blue tooth was only 12.95 from Amazon. So no big loss if it turns out to be a waste. There is a local Cert BMW shop here with dyno and all the toys a mechanic would ever want. They Said they'd charge me 89.99 to do a full diagnostic, compression test, ect and if there is anything wrong from the intake to the exhaust. they'd find it.

How did you get the readout? Which gauge did you use, do you have the Hyundai additional plugin?

I got mine setup and using the Turbo boost pid from the Hyundai plugin and it reads 11.7-27psi chich i Know is wrong, but I can't get it to read a 0 when engine isn't running.

Thanks. I realized i was using the Hyundai plugin turbo Boost gauge which seems to not account for barometric pressure...odd. Put in the Vacuum/Boost gauge and had to adjust -.03 to get to 0 with engine off.

I used the adjustment in the Vehicle profile. It says to adjust for some Mitsubishi, but I put in -.03 instead of 0 or -14.7 and it worked just fine. Now it reads what I consider to be realistic boost for a stock 2.0T in Phoenix, AZ. So, normal driving its only getting up to 12psi.
