After the first pull, Dan and Eddie review the data.



Since this is a street engine designed to be daily driver friendly, all dyno pulls were made on 87 octane gas. After about 10 pulls, the final data was achieved.
I want to thank my friend, and my engine builder/tuner, Dan Costello at Performance Only for the excellent job he did on the machine work, the building, the tuning, and the advice and guidance all the way through. Put me in the growing list of satisfied Performance Only customers!
