I was pretty sure itsx would let u change the ratio but can't find it anymore. Also ,I developed an issue I must a scraped somewhere and knocked the drive shaft outta alignment. It vibrates at high speeds I think around 85.

If you already have a tuner then you just have to go to tune and tell it to modify it. Then select gears and change ratio.
Just google your tuner model.
When I switched from stock 2.73 to 3.55 it was about 20mph difference.
