[QUOTE="wbt, post: 10969591, member: 113712"] Everything I have read/seen is that you do not have to pull the LT's to get the transmission out. I can't really comment about the stock tune other than it does have torque management enabled which will kill gains particularly in the middle. If you look at the blue line in the graph, you see that the car starts to show TQ gains over the stock headers around 4,100 and then TQ management kicks in and takes over until around 5,600. I.E. it closes the throttle blade to control the TQ. I would recommend a tune either way to get the most gains. We didn't need to make any specific A/F changes just with swapping the shorties. The tune already had the rear O2 sensors turned off for the O/R X pipe and that was all that was needed. Make sure that TQ management is disabled in the tune and you should be good to go. [/QUOTE]
