since realizing after i bought one, that a 180 doesnt realy keep the engine much cooler than stock, i went out and bought 2 160 stats one for the sub and one for the silvy, well a friend who is also a mechanic, says that i shouldnt install it until i get my tune, something about the computer not going into closed loop, because it never reaches operating temp. is this true, because i dont think i told allen about the stat, cuz i didnt have it then.
