first time i took the gto down to states and filled up on 92 chev/texaco i FELT the car ran better, but didnt take my datalogger so i thought nothing of it.
second time took my logger.
i was able to run an average of 2deg more timing in my whole band before knock.
filled with 94 again, knock came back and had to back off the timing.
all on 11afr, 17psi.
im convinced.
doesnt really matter now that im running meth inj.
after reading some of the comments here im thinking of trying shells 91. was always put off cause its same price as chev 94 and 3 less octane.
