But anyways i was talkin t gram and he said ut a 180 T stat in thats what i have now but i have a fastchip stage 2 and there site says to use a 160 T stat What one should i use? Gram said that i would never gt out of open loop or somethin like that. What one should i go for

go with the 180*, best for all-around driving. not too cold for winter, not too hot for summer.
