Who is BS'ing who?
I think it's pretty clear at this point that people who know how to tune (or at least care enough to learn) are the ones who get the better gas mileage. Of course when you have the attitude of "I just wanna go FAST no matter what it takes" you won't care if your car/engine combo is set up for less than optimal efficiency. Want to just throw on a new carb and go? Think about it for a minute, how much fuel do you think is wasted having a 12.5:1 A/F ratio at cruise? And where is that fuel going, OUT THE TAILPIPE and collecting on the cylinder walls to wash away the critical tiny bit of oil that makes it all the way up there from the bottom of the bore. Not only are you wasting gas and polluting you are making your engine wear out faster, all for NO good reason IMO. OK rant over lol...
