Road trip results real good

Took my recently repaired TC on a trip down to Skyline Drive VA and back to CT last week, putting on about 800 miles. On the road, I got over 30 miles to the gallon, running 70 - 75 mph, using the AC most of the time. Was glad to see this kind of results. I use 93 octane with a can of octane improver. Got several compliments from people on the car. After I adjusted the lumbar support, had no back problems sitting in there for eight hour driving stints. Also, with the new aluminum radiator installed after the accident, and a new air dam (Mustang GT style), that engine ran cooler- at least 20 degrees less than before.

You should do the mass air conversion, you'll get even better gas mileage. I just drove from Naples to Orlando for training. I filled up just before getting on the interstate and got...(drum roll please)
...41.9mpg.
I got there and back on one tank of fuel. I love these cars.
BTW, I NEVER turn off my AC. As a matter of fact we tuned the EEC with it on MAX AC since I always have it on.

Do you give the credit for that mileage to the mass air?

Both of your numbers are very impressive for a 22 yr old car, but even better it is as good if not better than most new cars.

I would say it is the largest contributor. My car has been lowered too, so aerodynamically that helps as well. I didn't get this kind of mileage before my conversion. It was good but not like this. SVOJohn tuned it but says none of the other cars he's tuned gets mileage like I do. I would also say that it's not just the mass air conversion, but the type of meter used in it. I have an Abaco 85mm DBX digital air meter. The signal is super-clean, providing extremely accurate air measurement which is key in getting good gas mileage. It's expensive, but with the price of premium fuel, it has paid for itself several times over. I would not recommend any other meter, period. They are subject to vibration, reversion and turbulence. All of which gives you a dirty signal. Your car may run OK but you won't receive any mileage benefits, your car will only be marginally better than with the VAM.
