Fueling & Injection - good air fuel guages?

been hearing alot of bad things about some air fuel guages, personally never bought one. so what are good brands, is :confused: cobalt good? lol sorry for being a newb.

The Cobalt is a good narrowband one. Narrowband ones are pretty much a light show though and they can toast your O2's. If you have about $300 you can spend look into a decent wideband one.

Currently running the "Dyno Jet WideBand Commander" Great unit. With a lot of features. Recording-logging, even has a settable warning light for any A/F ratio you so desire. Even has a few controlled switchable outputs for Nos, Meth ect.
