I have a 2010 LGT, owned it for about a week, and a Cobb accessport that is attached to it(currently tuned to 91 with some 93/92 mix in the tank because I am waiting for it to run out to switch it to stage 1 93 tune). Recently as it has been getting hotter(around higher 80s to 90s), I have noticed that my coolant temps stick over 200 and sit around 208. It has gone higher, occasionally in the 220s. Is this a warning sign, and if it does get even hotter is some extra maintenance required to keep it low. coolant level is fine.
Maybe this thread could be a deposit for all the cool running tips
