EGT Temps ?

Im new to all of these EGT temps and stuff so Ill post them and tell me what you guys think:

Cruizing on the highway 60-75 - 975
WOT threw 3rd - Most I see is about 1200
WOT threw 2nd - most I see is about 1000
Idle - about 500-600

I have the cartech pretty much ghetto set just to 45psi of fuel pressure with the vaccum source OFF the Unit... so tell me what you think..Im soon to get tuned and all but Ive been running threw gas like water..my milage really is bad and im not even boosting all that much

Where is your probe located? Mine is right in the front manifold, and it reads about 1100 crusing on highway, maybe 1250 if i am doing like 85 and up. Boosting 12psi, I am able to get them to 1500 3rd (redline) to 4th (5.5k) gear pull no prob. I obviously let up after that, but thats all with a 11.5:1 a/f ratio. I dare not go over 1500*F. Although I know this is the safest allowable on 91, even though I run 93 just to be safe. Then again, I have also top'ed 4th gear in my car on a couple of occasions, which I am certain is past 1500*F.

mine is in the rear branch on the Y pipe and see about 1250-1400 while cruising (70-90mph) on the interstate depending on the incline. Under boost the drop a little since I am still rich.

~900-1000 while cruising. ~12-1300 while under full boost. That's tuned to 10.5:1 on the dyno.
