The timing doesn't cool anything down it just puts more heat into the cooling system and heat soaks the piston rather than spit it out the exhaust. X amount of fuel still gives Y BTU's, we just can't measure it when it is in the cylinder too long.

After its warmed up, cruising on flat interstate at 70 it holds between high 600's and low 700's. (start up temps are with the exhaust brake on, also.)

I've been getting black smoke right on start up (cold start only), and have been trying to isolate the facts..but started second guessing myslef when I started looiking at the EGT's. It doesn't seem like leakdown at this time - no fuel in the oil, no white smoke at all, and no rough idle. Smarty is now on level 3, XZillaraider is off. Air filter has been cleaned. Power does not seem to be up to snuff.......but that could be in my mind also.
