Just trying to get some input. Think my EGT probe took a dump. Was working fine no changes to the fuel map and it just decided to give me these crazy readings/spikes in temp, like 2400F and then right back to 1200/1300F. Not even when driving just revving to 2000RPM in the shop it would do it within 5 seconds. Never seen this before. Normal temps throughout the powerband while driving, boost included, avg 1600F or so.

Probe is in the R2 runner bout 2-3" downstream. The only thing different was recent addition a Meth - 30/70 mix approx. Thought maybe if the slow burn of the meth lit the runner on fire could have maybe melted/overheated the probe and ruined it. Just spitballin here. Any input would be appreciated.

Thanks,
Erik.
