I think a tune would be the way to go.
You don't say the mileage; but you wouldn't want to add a lot of boost and break something on an older engine.
I have to take exception with a statement made earlier, a supercharger will increase low end torque, and as he said, it will also add to upper end horsepower.
I had an Olds with a Buick 3.8 that was factory supercharged. The best engine I ever owned, it would break loose with part throttle.
I don't think I ever towed with it; but I know it would have moved a good size trailer.
