No problems all around. I agree that is a lot of timing, cruising temps are 725 - 775 F* & nothing over 1200 with WOT. 21 -22 MPG.

Most likely making negative torque. More or less have expanding gases in the cylinder before the piston makes it to the top. So part of the power is lost in that part of the stroke and then when the crank passes TDC then the expanding gases are pushing hard. EGT are higher than they should be... Also if you monitoring the oil temp you'll notice the engine oil temps will be higher being there is more flame front in contact with the cylinder walls longer so the coolant near the oil cooler get heat soaked and oil temps rise. 

 

66 MPH = 2,000 RPM = 550*F EGT's = 162*F Oil Temp 

 

55 MPH = 1,600 RPM = 450 EGT's = 158*F Oil Temp 

 

Anything that is generating heat is a loss of power... If you truly getting all the power consumed all your temperatures should be low. The only way I could reach 725 to 775*F is hauling my RV on flat ground or climbing a 7% grade typically.

 

Already got to 28.04 MPG on this tune... 425 miles at a half a tank typically if I'm running light foot.
