While this may not be a popular opinion now days, and yes I'm older, if you want to be successful at bracket racing, the EGT should be the least of your worries. Just run your engine in a safe rich/lean area, period. It's just not a reliable between rounds tuning tool as far as I'm concerned.
You need consistent reaction times, consistent 60' times, and enough passes under your belt that you feel how the car is performing on each run. Your experience and analysis of each previous run, along with any weather changes, will guide you to the next dial in.
Although it happens on occasion, very few cars will repeat, repeat, repeat. You need to learn how to drive the top end in these races, and it will come with time in the car. Taking the stripe full on, pushing the other car out, brake tapping to not take too much stripe, etc. is all part of being a good bracket racer.
I hope I'm not coming off harsh, it's not my intention at all. I'm confident as you make more passes in the car, you'll get it.
Hey Man, we're in the same state.....Maybe sometime I can roundup enough $$$ to come see you make some runs. I'd really enjoy it. :thumleft:
