This was going to be my next question to find out if people had really felt much difference in actual performance with the power it has.
On my RAM I have 800 torque and 370 HP so a little loss won't be that noticeable I feel for what I do with it. It has 3.42 gearing and would go to 3.23 with the 35s.
You will lose some performance for sure, but may not really be noticeable.
If it's slow to get off the line now, it will be even slower. If it has to downshift now to get up hills, it will have to sooner.
Everyone's different in what they consider adequate performance. Some of these mall crawling jeeps couldn't get out of their own shadow, but most of the drivers don't care. My guess is it will do just fine.
