Hidden/Discreet Boost/AFR Gauge?

I'm installing a supercharger and looking for the most discreet or hidden option for monitoring Boost and AFR. I prefer not to have an obvious added gauge in my interior. Something hidden or able display on my phone would be the most ideal.

What are my options?

Thanks

I just found a company called PLX that makes modules and sensors that transmit wirelessly to iPhone and Android. This might be the way...PLX SM-Pro module.

 

I've used PLX before on my M3, and I wasn't really impressed.. I still have their Kiwi 3, actually. It's been sitting in a drawer for YEARS. They come off as a Sharper Image type company. Check out all the various things they make....I'd look elsewhere at that price point.

That and the fact that they just told me that the dongle I would need to wirelessly transmit the data to my iPhone is not currently available and I should check back late next summer, lol.

But I appreciate sharing you sharing your experience
