blew trans have questions for replacement!!

so i blew the trans in my Suburban last week im puttin a used one in and have a transgo hd shify kit along with the vette servo.im also putting in my trailblazer converter at this time.my question is i havent had a tune put in the truck yet because im doing a 6.0 swap in a month or 2(still gettin parts together).but i figured sinced the trans was out i should do this stuff.will the higher stall effect the daily driving of the truck wthout a tune??i dont wanna damage anything.thanks..VJ

Truck owners have been doing higher stall converters and shiftkits with no tuning for a long time, with the stock line pressure and small tbss converter, you shouldn't have any issues with no tune.
