After installing and using the lockup torque converter switch and not really going over 60 mph my mpg averaged 14.36 a gallon

Was that all highway or a mix? There are a couple dozen things that affect fuel mileage. Driving habits, vehicle weight, altitude, temperature, traffic, air filter and tire size to name a few. For instance, I can influence my mileage by 2 or more MPG by just doing jack rabbit starts and stops. I'm sure you have heard of driving as if there were eggs on the accelerator and the brake pedal. Just a couple days ago a 2nd gen passed me with a haze coming from the tail pipe. I know for a fact that the driver couldn't see it in his mirrors because it dissipated quickly. If you can honestly say your driving habits are good it is time to look at tuning if that is highway mileage.
