Put a rock under the loud pedal so you can florr it.

Bell,
Best computer that I know of to deal with that issue is a lite right foot.
I'd guarantee fuel consumption will correlate very closely with "foot force".
Lots of luck! Lincolnlov

well, you could decrease your gear ratio, which will help a little. there are 3 ratios on these cars...3.07, 3.31, 3.58. depending on which one you have you may see an increase in mpg with lighter acceleration and a lower(smaller) gear. if you somehow have the 3.58's, i have a spare 3.31 set, and a complete differential with 3.31's in it already...but chances are that those are the gears you already have.

Swapping rear gears like that will only help if he does allot of highway driving. If he does allot of city driving then the higher numerical gears would help more for gas mileage due to less load being put on the engine to get the car moving again and again.

Actually, quite some time ago there was a study about the relative benefits of lower gears and MPG in city driving. IIRC (it was quite a few years ago) the conclusion was that as long as your transmission gears were appropriately spaced, medium to quick acceleration while short shifting resulted in the best mileage using lower numeric rear end ratios. The explanation at the time was that getting to the desired speed as fast as reasonably possible while short shifting the transmission resulted in less pumping losses because the throttle would be in the open position sooner and maintained in that position while pulling the highest gear possible.rocket5979 said:

remove the COP from every other plug - I hear 4 cylinders get much better gas mileage j/k
actually - a better tune, free-er flowing intake and exhaust, a good tune-up - should result in better mileage. Real-world - you simply get where you are going quicker. It takes alot of mileage savings to pay for the mods....

I don't put much weight into "studies". They are usually inaccurate or just plain biased for one of many reasons. I go off of my personal knowledge and experience of both cars and physics.
Tranny gear spacing will definately aid in getting better MPG and smoother powerband. However, rear gears are another extension of that to aid even further with multiplying the mechanical advantage to the wheels. The only way to really equal the added affect of regearing the rear diff is if you added another gear to the tranny.
