what is the best A/F guage out there? and how much can you get it for?

what i mean is cleanist, most professional looking and what price can you guys get it for? from where?

if anyone on the board knows the answer to this question, it would be the forced induction guys!

a/f gauge = waste(unless it has a decent warning fucntion)IMO, spend it on a good EGT gauge instead

the absolute best is a wide band.. second best is a tomei or equivalent. don't waste $ on an autometer one.

btw, i have a tomei for sale if your interested. (shameless plug)

i heard Defi gauges are pretty good

is this gauge hard to install? what does it involve doing?

I recently bought the Innovate LM-1 wideband O2 sensor (uses a Bosch LSU4.2 sensor) and datalogger. http://www.innovatemotorsports.com/

I haven't installed it just yet, but I'll let you guys know how it works out. You can use it to drive an optional gauge:

what is that guage where it just shows you if you are running lean or rich or right in the middle with a light or something?

Yeah, that's the one not to get. It's made by Autometer. It tells you if you are rich or lean, but not how rich or how lean, so it's useless for tuning.
