Yeah I bet you have a bad probe. I've never seen 2-300* difference. Most I saw years ago was 50* at WOT. If you do maybe you have a angry injector
I guess I could swap the probes side to side next week and drive it for awhile, fortunately I bought the probes with weather pack connectors and they disconnect real easy, no heat shrink to deal with. As much as I have read on how to properly check injectors not sure what is the proper way...
and the EDB videos show at one point EGT's being different.?
Here is what they looked like after driving for several hours, one is in park the other in neutral on my stock DSP5 tune.
