I installed a 180' T-stat. I did notice the temp gauge did go down to right above the 1/4 mark upon start up and idle. I felt a noticable responce to the gas pedal initially. after driving for about 30 min the temp went up to half way (that is where it was with the regular T-stat 220 degrees). I do the the Diablo and change 8 temp setting from 230 degrees to 195. The Diablo gives 8 settings- with A/C on and wit A/C off. I turned all them to 195. how can i keep the temp down on the engine. should I turn the temp setting to 180?
this is a t-stat part # 160 from O'Rielly's
