as long as your running stock turbos, or another quick spooling VGT setup I think the lower stall will do really well, you run lower tranny temps for towing an what not I think with the lower stall, your egts might climb a little quicker in return though, like monster said it depends on what your doing, im happy with factory stall speed so I probably wont ever change but if i did i would go lower stall..i like the driving feel of your engine having a more direct connection to the rear wheels like you get with the lower stall
