Jb4 oil temp guage hijack for boost? Question

So I hijacked the oil temp gauge, and was wondering 70c 120c and 180c what do these translate to in terms of boost? I know that at whot ill hit 140c on map 1. What does that translate to in boost? Thanks for the help

Ok so in between 10 and 20 means I'm hitting 14 psi if not a little more on map 1...?? Thanks for the info

well the gauges are more to get a sense of where boost is at. It's hard to an accurate reading especially on boost ramp up.

you're in the ballpark
