Well ever since I got a chip with Lidios tune seems like every so many days when I start my MM and drive for a bit I start to overheat. Now here is the weird thing if I turn the vent on high at 90 the temp drops right back to normal and then I turn the vent back off everything becomes normal again temp goes back to half way and everything runs perfectly fine and it wont overheat till a day or 2 later it will do the same thing. Just wondering if anyone else has had this and what it is. Wondering if maybe its something with the tune. Also wondering if maybe my thermastat maybe is just struggling to open when I get her started from the cold. Any ideas???
