VERY NICE MONITOR !!

Extremely fast response to the engine and EXACT measurement of your exhaust flow and fuel mixture. I LOVE this gauge in my dash

It works, so far...

Some say, "i tune by ear", some say "you don't need this".... i say, it helps, good product, takes the questions out of the equation if you understand tuning.
