I was wondering what my EGT gauge should be reading during normal driving. My reads around 3-400 C at idle and 5-600 C while drivng at all times. I have

Greddy intercooler
720cc secondaries
S5 turbo
Apexi AFC
HKS exhuast
racing clutch
walbro fuel pump

And a couple other unimportant things. I bought the car with all the mods done to it. I never paid to much attention to the EGT guage. I knew that at 70mph I should read 700 C. The last couple times I have driven at 70 it has read around 600 C. I haven't noticed any differrence in the cars driving. Hasn't slowed down. But I'm not sure how much 100 C will make and if I will notice a difference. This is a long winded post, just looking for and suggestion or thought just want my 7 running right. Its my baby!

It will vary depending on the sensor's location. Do you know where its located?

sounds fine.. "normal" driving doesn't really matter anyways. it's under full throttle and full boost where it is important. don't go over 800C. I see around 750C after a 3rd / 4th gear pull

that is in the downpipe, next to the 02 sensor. as posted above. the numbers will change depending where it is.
