I have an autometer boost gauge, it read 10psi, and my afc read .53 bar, which is like 7.7psi, is the afc like RIGHT on, and my autometer boost gauge just blows? and is it all boost gauges that suck or just autometer?

 

i would trust the afc but then again maybe u should try another boost guage

maybe a friend can lend u his

 

I wouldn't trust the AFC at all. I have never had a good reading from any of those *******. Maybe try a different gauge?

The gauge is Brand new, like out of the box

 

I would trust the gauge also. Whenever I tried to read the AFC it was always off for some reason.

 

Analog style boost gauges are hard to mis read things. Swap it out and you'll know your answer.

 

why does this matter again?
u wanna push ur engine to the limit?
