Those who are running the TRD charger and have an aux temp gauge...what are your engine coolant temps while driving on the flat at 50-60mph, with 90ish degree air temp? I just installed an auto meter temp gauge and holly crap my engine is running hot! I think my new gauge has to be off. I am running @ 220-230 (according to gauge) at the above mentioned conditions. While sitting in traffic with AC on and low RPM's (less than 1800) temps will creep up to 240 and my AC shuts off? I thought the AC shut off at around 226?
