Couple of new questions for all my favorite helpers.

[71C-10DAD]

1st off thanks again you guys for all the help. Hope you all took a look at the pics that i posted. So you have some idea of what you are helping me with.

Now on to the questions.

1. Why when i get on the highway or interstate and go to get up to highway speed does it spit and spudder. When i reach 70 it doesn't do it. But if i am cruizing along at 70 and hit the gas it does the spit and spudder thing again till i let off.

2. What gears would give me a best acceleration and which would help improve my gas mileage.(Or do those go hand in hand.)

3. What do i need to do in terms of showing those mustang kids up. When i comes to lighting them tires up at a stop light?

4. What seat gives you the best big man fit when trying to keep it to where three can ride in the truck.

Thats what i have for now thanks again for all that answer back.
