Custom tunes are much better than the canned from TS. I recently switched to PHP tunes from the canned tunes and I'm much happier with them. I've run four different chips in this truck and so far I like these tunes the best. Stick with the TS style chip so if you want a reburn you won't have trouble finding a good vendor. TW, PHP,Gearhead,Beans all have good reviews so you really can't go wrong with any of them.
