What is the difference between Dyno #'s of SAE vs STD. I just got my cobra with my 2.3 whipple tuned today and the #'s were 592HP & 549TQ @ 17lbs, and the tuner changed from I believe SAE to STD and the same runs #'s went to 604HP & 560TQ. Is it just a different spot were a sensor reads? I forgot to ask while is was there and thought someone here could enlighten me.
