i just bought a 07 tbss. has a baby cam, not sure of specs. has a 4l80e swapped in with a 3800 stall. found the tune in this was hacked together as some how it was tuned when they has the o2 sensors in the wrong banks. so they just turned off everything. need to start from scratch.
engine runs pretty good now. but the trans just doesnt feel right. i havnt driven a 4l80e before but i feels like line pressure is not turned up. just feels sluggish. also noticed tcc never engages. can some one take a look of the tune and just point me in the right direction.
