claymore.. your the man!

are you sure i would need a aftermarket water temp gauge? the standard eg civic ones seems pretty accurate. Not so much in saying the exact temp, but i know when the car is a good warm running temp... and when i am also getting close to trouble before anything becomes compromised.

Deffinately Boost (psi) and oil pressure would be my top 2. What are the benefits of running a wideband a/f (besides being able to tune on it?) would yoru a/f ratio evey change away from what the car is tuned at?

Seems really a toss up now between oil temp, water temp and, A/F
