[Mongoose]

On my stock boost gauge the needle usually hits right between .09 and .1 so I'm pretty much right where I should be. For convenience sake I pretty much just think of each mark as 1.5 psi, it's actually just a hair less then that but it's a good way to gauge boost pressure when not at WOT. If you look at it this way then .05 mpa=7.5 psi, and thats pretty close because .1 mpa is 1 bar and that might as well be 15 psi. Again each mark is not EXACTLY 1.5 psi but it is pretty close.
