Some ways people get better milage is by replacing the fuel filter, getting a oil change and putting in new spark plugs. But your best best is to get a ubend delete to help with exhaust flow. That costs maybe 40 bucks at a exhaust shop. People also do a air intake. Use the search button to find the answers to most of your questions, there is a ton of info on this site.

Thanks for the warm welcome GTP Brothers.

Fivefinger. My GTP is exactly the same color as yours. Except I have chrome rims.

I am averaging right at 24 mpg. I do more Hwy driving then City & reading that you get 33mpg is making me wonder why I am not experiencing the same milage as you do.

I am going to replace & do the following to fix my milage problems

Autolite 104 spark plugs
Fuel Filter
New Supercharger oil
New Stock Spark Plug wires

I will have to look in to the U-Bend Delete. Can a exhaust shop just fab up a U-Bend delete & will it change the exhaust note of my GTP. I like my car to be quiet
