I have a 97 Dodge Ram ss/t with a 5.9 with a Powerdyne supercharger. I have read a post just a min ago talking about changing the gears from 3:55 to 4:10's. If I did that would I get better or worse performance? Would I get better gas milage? right now im getting 15-16 on the high way with 0 boost from the charger and it runs great. Just curious. I know how to do a gear swap so thats not a big deal. What do you think?

 

Depending on what size tires you have, you could get the same or worse gas mileage.

But you should definitely notice more jump off the line.
