I don't have any issues with underpowered with my 3.4 in there , and especially once I get the SC put on there.I do probably do more highway driving out here , thats why I wasn't sure what to expect in difference.

I don't really want to go any bigger than the 33", I am happy with that size , and don't plan on a SAS in the very near future , maybe 1 day down the road , maybe then will go up a step to 35".Was also thinking of 1 day changing out the tranny as that is a weak link in these trucks.All possible future projects down the road.
