Hello Everyone,

I am just seeing if there is anyway to get 1500 r.p.m or lower for better gas mileage and performance for my car at highway speeds?
 


Well, honestly, you're not going to gain anything by dropping your RPM's that low. The problem would be lugging the engine...which is very bad for them. The best way to get the best fuel mileage is to watch your right foot and make sure your car is running up to snuff; you know, new plugs, wires, air and fuel filters, oil change, new O2 sensor, low boost turbo, and tune. Obviously the last two aren't really necessary, but many people have seen better fuel economy with a turbo over the factory SC.
