Re: egt's pre/post turbo
Pre-turbo readings will tell you how hot the exhaust gases are as they exit the engine and head toward your turbo. This tells you how hot your engine is running and is handy for preventing catastrophic failure to the engine and turbo.
Folks with pyros in both locations on the same truck have reported some very drastic differentials in the two readings with the post-turbo readings being well below that of pre-turbo. They also report that the differences are not linear. So nothing of significant value can be obtained from a post-turbo reading that would help prevent a catastrophic failure. It might be handy for knowing when your turbo has cooled enough to shut down, but that's about it.....
