I have the gauge no picture,It doesn`t read in PSI or Bar, Just MPa or Mega Pascals, so on a standard wrx goes up to around 0.1 under hard accelerationin in a high gear before it backs it back down to around 0.09. and it doesn`t obstruct anything really important on the instruments. But if thats what your after i wouldn`t recomend it for hard driving, having to avert you eyes to the instruments to see whats happening which is not good when it`s hurtling from 40 - 80 mph in third gear. The a pillar ones would be better for tha. I would put a piccie up but mines 8000miles away at the moment, being moddy coddled by my parents. While i`m freezing my **** off, hope this helps.
