Both goals torque and mpg are waste of money chasing. NA Torque is mainly dependent on displacement most stock to mild engines will produce 1 to about 1.15 lbs-ft per cid. More CR good exhaust, less restrictive intake side etc.., maybe a mild cam.
Fuel mileage is hard to recoup unless your spending crazy amounts in gas a years, if you spent $2500-5000 a year and increased mileage by 10% would be a $250-500 savings which you could easily spend multiples of that chasing mileage other than basic tune and setup.
usually cheaper to dump the money into the tank when doing anything above the basics.[/QUOTE]
