Help refresh my memory. I have 2 cyl on my car that are runnig hotter than the rest, most are at 290 at the exhaust flange but the number 3 cyl is running like 520 and the number 6 is running 425 or so. I just got this thing put together (see sig) and have about 40 miles on it. It runs great bocoo power but I checked the temp with one of those laser temp readers just for the hell of it. Is it too much fuel or not enough fuel that causes this?? I can't remember. anyway another tid bit is that I still need to put in a fuel pump and reg and set the pressure ( no money right now). so am sure the car is a little lean right now.
