                    I put 2 EGT's in the standard position of 4 inches from the port, and really there was no difference except that I kept burning both off.  Their usefulness, and one will do, is to regulate high temps with either revs (lower) or a richer mix to lower the high EGT. 1800 degrees F is quite warm and will test the exhaust system.  The probe just lets you know if you are wasting your time or actually achieving something.  Once set up they are just another thing to worry about in my case, so currently running without.

For those of you that are using the stock manifold, where/how did you locate the EGT probes?

With an O2 sensor, I'm not sure that a single EGT probe has much usefulness. However, one for each rotor would give indication of mixture imbalance between the two rotors.
