i have one of these. unless its 80 degrees outside it actually works TOO well while driving normaly. if its kinda chilly outside, and im driving on the highway at 80mph it wont even get above the lowest reading on the guage "140" i think.
but at the track, ive never seen it above 210 with the kit, using royal purple. and thats going balls to the wall for multi lap.
downside imo is that it cost me 1100 with installation........
