To hot?

Running at 65mph empty I am seeing 800 deg egt temps and about 10 pounds of boost. I have a 4" turbo back and no tunes. Getting around 18 to 20 mpg and power feels ok. I just changes the fuel and air filters. Just want to see if ths is normal. Also trans is about 145 to 150. Is that ok?

Maybe a head wind is causing the 10 psi sometimes ?

that could be it, but he says this like its an average of what he is seeing, you wouldnt always have that headwind haha. And at 10psi of boost i wouldnt think you'd be seeing almost 20 MPG?

I guess that may just be the difference between a SD turbo and a OBS turbo, but i am under 5 when crusing and i can spike it to 35 if i really try
