I have an 02' Ram with the 4.7 L engine. Well I just put 35" tires and it and it seems like it doesnt have the get up and go it did. I already have a K&N intake, Jet Chip, Flowmaster Cat-back exhaust. What can I do to get some power back?

 

The best way is to change your gears...at least when I had my Jeep and went to big tires that's what I had to do.

 

It has 392's now. What would I have to go to?

 

2 gear sizes taller should do it.

 

4.56s - I have the stock 20s (33" tires) and went from 3.92s to 4.56s - absolutely no regrets.

 

Who did your gears and how much did it cost? I am thinking about having it done in the spring. I read that with the 4.7 it makes a big difference
