Zoo Dad - How good is it?

[Tail_Gunner]

I didn't really see a performance improvement. What I observed was lower EGT's and engine operating temps.

The only thing I bought was a new pack of saw blades.

I saw no improvement in mileage or power, but I did see the EGTs go down a bit. I bought nothing; I had the blades.
