Just to let you know the ethie helps cool the intake charge which in turn lets you mess with timing more than just 93.
Hence when I was tuned with our 91 oct with the ethie the HP was about the same as the 93 oct. I was able to bump up the boost more to get the same power.
So to recap.
91 oct with ethie gives me 325 whp at 22.5 psi on a mustang dyno
93 oct gave me 325ish whp at 21 psi on a dyno pack.
now if you do the math. a mustang dyno reads much lower than almost all other dynos so I might even have gained some power going to the 91 oct from here.
