For it to be adjusted to its best, you'll need a tune. If you want it close, you can use a handheld programmer. The gear swap will throw off both your trans and speedo. Both will need to be adjusted. When I went from 2.73 to 3.73 in my 'bird, I used my HPPIII to set it temporarily. Later on I had the car tuned and couldn't be happier. If you go the handheld route first, make sure to remove that tune BEFORE having a custom tune done.

Tuning the trans shift points can make the car more fun to drive and more to your liking. A hand held can not adjust the part throttle shift points nor the TCC apply/release times. So you get more satisfying results from a tune.
