Alright, kinda lame question...also did a search and couldn't find enough
I'm a diesel guy that went back to gassers, never seen this A/F Gauge so i'm just looking for details on it, I think I have a general idea of what it is but some more info on the importance of having one of these would be great
(Looks like Innovative Motorsports Wideband is the choice product)
Thanks

 

Why do you need one S/C Turbo ???

 

so...if you have a S/C or Turbo would be the only reason?

 

in short yes
