Ok Im wonderin well im boostin my f22b2 at 8psi
Now im wonderin that im gettin the APEXi safc
but if i want the gauges to work like the boost gauge, egt gauge, and the turbo timer, do i need to get somethin else for the reading could work?

 

Your grammar sucks the big one bro.

All gauges have there own sensors so if you buy a boost gauge, it will have everything in it you need to read boost. This applies for all gauges as well as turbo timers.
