I'm installing a Saleen blower next week. I want three guages:
1) A/F
2) fuel pressure
3) boost

I want to do this the cheapest way possible. I understand that I need a wideband to monitor the A/F, then a guage to plug into the wideband to display the A/F reading.

But what about fuel pressure and boost? Are these simply mechanical guages that plug directly into vacuum lines or something?

Basically, what I'm confused about is...what guages plug into the wideband and what don't?

Thanks!
