the pinicle of n/a racing, the boys run 8 a/f sensors in there exhaust
pro stock engines.

i have seen both headers on dyno, it is REAL easy to tune the fuel curve, and give the engine what it wants...

That is what we do. Use them on the dyno to get the cylinders balanced.
the EGT's are too slow for tuning. They give decent data and will tell you if you have anything going away.
I use the EGT's in the car but only one wide band on the passenger side collector.

Most Pro Stock guys run them on the dyno only.

Robin hit the nail on the head for what I'm trying to achieve.
I've used EGT's for my drag racing data, but you are right they are too slow and are great for reference when you download your data.
I'm wanting to know what it takes to manage each cylinder and keep the engine happy.
Thanks for they replies.
