Hey bro, anything is possible in the performance realm. I know what my rig can do and what it does. I to installed my gauge and know that its reading correctly, so take it or leave it but them are the facts ma'am.

Pre-turbo being exhaust manifold.
Post-turbo being the exhaust downpipe (at least that's where mine was)
If someone had a pre and post turbo gauge installed on the same truck and had a separate gauge monitoring both, and under load, the Pre would ALWAYS be higher.
The Pre temps heat up WAY faster and cool down faster.
The Post temps heat up slower and cool down slower
At least this is my experience.

The "post-turbo" reading can be up to 400F lower than "pre-turbo". If you are seeing 1300-1400F "post-turbo" you could be at 1700-1800F "pre-turbo" (this is not good). You really do not want to see temps above 1350-1400F "pre-turbo" (950-1000F "post-turbo)except for very short periods. Yes you can briefly run them higher, but the EOT temps climb rapidly and take along time to cool back down. High EOT temps are much harder on the engine than high EGT's.
If you are seeing 1300F "post-turbo" you need to back out of the throttle and not let the EGT exceed 950-1000F "post-turbo" when running down the road, especially for extended periods.

Prior to installing the new turbo, I would peg the 2000* EGT gauge running the 1/4 mile. Now, thanks to the increased air flow, I'm seeing it max at 1600* on the strip. I haven't fed it the Water/Meth or NOS yet, but those combined should keep it under 1300* and give me WAY more power! 
Hopefully gonna see the track again this Friday or next to see where she's at now.

so chad and monster before you guys start bashing take a look at what's going on i was not trying to bash either one of you. i know what i'm talking about, i know about egt's and i realize that hod rodded motors will make some extreme temperatures i was in no way trying to talk **** about either one of you.

LOL! I keep Matt laughing at my Redneck hyde..
I got my Ultra Comp Street file and I was sweating so damn bad.. I had him on the phone for 2 hours while he listened to me run up and down the road pounding it.. But one thing is for sure I didn't puke no damn coolant like my Livewire was 
Now to finish the other work and get it head studded!
