Just got this Boss and I'm seeing head temps reach 220* just cruising. Is that normal? I just sold a 2013 GT and the head temps averaged around 207*and hardly ever seen it go above 210*.
Looks like I have nothing to worry about. It was in the High 80s and humid yesterday. I was only concerned because my GT never got above 210. The GT had long tubes and good tune so thats probably why it ran cooler. The Boss will get the same soon. BTW. I am loving this Boss.
Do you have a 2013 LS? It's hard to tell by your avatar
Anybody have any data on head temperature after the MMR cooling mod?
