ahhh, gotcha. Becareful setting up the eboost2, lots of people have blown their motor.
to the op, i would get a/f ratio, boost, and oil pressure gauge cuz we all know about the failing 3v oil pump.
i would get those aero gauges that have dual readings on each gauge and have boost and a/f constant and the other gauge cycling thru oil pressure, temp etc.. alil pricing but better than having a million gauges in ur car.
