Default egt probe location

Would locating an egt probe inside of a block off bung plug where the stock 02 sensor fits be too inaccurate for egt readings? I really do not want to poke the oem headers for probe location near valve..

After a lot of reading, it should be accurate if u plug it in the headers.

Default egt

you think its better to read the EGT, or wideband O2, or both?

im also thinking of installing EGT bungs.

Im hearing alot about cyl #3 being difficult.

Multiple sensors? i.e. one per bank?

^ to get the best tune possible.....EGT + Wideband.

To be able to tune each cylinder, you need an EGT on each cylinder.

Everything i've read to date says put it in the header 3 inches or closer to the exhaust port of cylinder 4, which is the longest and thus hottest.
