I prefer the O2 method but it is fair bit more expensive for sure than EGT's, not that either is "cheap" The fuel we use also seems easier to deal with using O2's than EGT's. Although if it gets to rich it can sometimes read lean on the sensor..Oh the joy of racecar tuning.
I hear ya, all part of the fun, I've been watching you tube where they picked up 60 hp by staggering the jetting as below....but they were using O2 sensors rather than EGT sensors, there was a surprisingly big swing in the jetting !! (We got our tent T/R in 2014 BTW if that's any help
).

Neat, I can see a row of V-net Tees
but cant find the EGT amp boxes
Snout bars are on the other side on the inner fender on mine
We used a USM for our engine monitoring but I'm looking at more (as ya do
)
