Just bumping the timing up 3* and running premium will completely change the whole torque curve and bring it in sooner!
The snorkle could be helping too as cooler/denser air will carry atomized fuel in suspension much better!
I will have to check the timing. I have always run premium in both.
-How do I find that vacuum line and do I just disconnect and clamp it to improve milage? For now milage may be more important. Are there any negative effects to this besides less power?
-I have heard that different pulleys are hard on the engine.
