I am located in the super heat of Houston TX. I have the GTM competition oil cooler and my temps never go over 195 or 200, and may I add this thing is huge. I have gotten it to 220 but thats cause I was ripping on it really hard for about 10min, and at the time I had a real rich tune for 91 oct instead of 93. Im sure now it would go up a little higher on agressive street driving conditions now since the tune I use on the daily now is little leaner.
One thing I would like to see though is, the capability to get up to temps much quicker after a cold start. I can drive 20min away to my office sometimes and finally just be getting up to 180-190 by the time I get their. I dont rip it until it reads 180 or more so it makes for a granny drive to the office every day
