My mate owns one and he has put a boost gauge in the car and because we have no manual for the car we can't figure out what is wrong, i think it's that he hasn't disconnected the old guage however he informs me that it is electronic (meaning that there is a pressure sensor inside the pipe) not mechanical. I was wondering if anyone can back this up as i don't wanna pull it off then have to put it back on.
I know it's not working properly as the original is in mmHg and this in psi and I've work the calculations out and his new guage is showning 5 to 6 psi when it should be showning 10psi.
Any help or advice would be great
