It has the 3.73 axle in it and I'm at 1930 RPM at 55mph with the stock 205/75-15's. The scangage was off about 15%, I have the displacement set up correctly. It idles at 800 rpm and it goes into closed loop after 4-5 blocks of driving.

I can hear the fan at start up some days, but the roar is gone before it goes closed loop, the fan clutch seems to be working fine. Voltage is around 14.2 and the AC compressor is not engaged either.

Didnt get a chance to dig into the exhaust manifold this weekend, but I'll let you know what I come up with,
