Re: Strange EGT's (CDooMe2)
I dont know how long the drive is but prolonged heat in that range does embrittle the head and heat soaks the quench area which if hot enough could detonate, I like running my car real rich on the highway - its a trade off. I am pretty sure running full 3" exhaust would lower temps by 100C. also consider backing off timing a couple of degrees as you obviously have too high max cylinder pressure under zero load. this may cool things down a bit two. also setting cams to overlap more will also cool things, but not make more power.

Re: Strange EGT's (CDooMe2)
I used to have the same problem except my egt's would be around 780 c while cruising on the freeway. I had a 12:1 fmu with 310 injectors. I recently swapped out the fmu disc to an 8:1 and adjusted the fuel on the v-afc and my egts dropped by 70-80 c while cruising. I was thinking that when I had the 12:1 fmu I had to pull more fuel(ex:-20%) then with the 8:1 fmu(ex:-15%). So while cruising and not boosting, it was pulling out fuel making the car run lean and have higher egts. What fuel controller do you have?

The EGT's are fine. But here's a solution to your money problems. I have a few friends that need to get tuned, you can try that and I'm sure they'll give you a few bucks in return.
