CTS2 boost level incorrect with add on boost sensor

[BlackHillsHD]

Installed a CTS2 with the add on boost sensor on a LB7. The sensor reads about half of what the computer boost sensor reads. Am I missing something with the setup in mystyle? I selected "PSI gauge 0-50" any help would be appreciated.

Doesn't the factory gauge see absolute pressure (turbo pressure + atmospheric) instead of just system pressure?

Isn't their add on sensor 0-100?

Yes the sensor is 0-100 but when you pick options it gives you 0-50 and 0-500 I am guessing I have to add in atmospheric but I don't know how to scale it.

I found the 0-100 on mine and it reads right. its in there. that was somewhat of a pain in the ass the first time get it figured out. I also have drive pressure and it reads correct too. I'm pretty sure there wasn't a 0-500 psi on there.

Okay, I will have to look again in the morning. Don't have it on my computer at home. Thanks
