See, you would think that, but my experience hasn't been that way. I think even though the engine is spinning faster, the reduced engine load offsets the high rpms to some extent. *shrug* W/o having my 4th gear any more, no way for me to test.

My DIC says I average 22 MPG. And I drive 80% highway .

I know I need a more efficient tune based on my A/F ratio on a dyno taken several months ago. Just can't afford to take it to Intense or ZZP to do it. I would like a tuner so I can do it myself but its my DD and I'm becoming less weary to experiment on it.

I need tuned to bad.

well i beat my own record today 159 miles on a full tank im going insane over ehre lol gas is 4.20.You guys really think a tune up will improve MPG by that much

I would like to know your driving habits. Do you let your car warm up? Do you start it and drive? How many stop lights do you sit at? how long is each light? How far is each commute?

Run a can of quality fuel system cleaner the next two tankfuls. I like seafoam, lucas, BG 44K or Berrymans B12.

If your car is not a GTP, do not buy premium gas.

How does your tire wear look? Get it aligned.

Change your Air filter.

Buy some mass air flow cleaner and clean the crap out of your throttle body.

Sure theres not a hole in your tank?

yea ill deff going to put the cleaner.Ive been puttin Premium in a car ever since i bought it couple of years ago.I realy think premium makes your car drive better.New filter got it 2 mnths ago tires look almost new still.As for the rest of the stuff im going to autozone tomorow lol

Zalfrin i checked it yesterday accualy no hole

plugs wires 02 sensor throttle cleaner fuel system cleaner fuel filter.Is that good enough or more thingd avaliable

I used to always get things done in shops but im tired of being robbed there thats why its all new to me lol

THANKS A LOT FOR YOUR HELP GUYS

those plus properly inflated tires are the standard list for improving mpg. don't waste your money on premium, you don't need it.

When i just bought the car people told me to put synthetic oil and premium gas so ive been doint that for a while.Does it really make no difference

how much air should i have in the wheels

I had a professor at Kettering University (formerly GMI) that said premium actually doesnt do anything better if your car doesnt need it. He said its good every once in a while to kind of clean things out, but not necessary. Since you have a gt, no premium necessary.

i mean in the tires
