Plus the 5.0 is an higher rpm motor (stock), they can easily rev to 6500-7000rpm which helps hold the gear longer and putting your shift recovery at a greater rpm. Swapping to 6.1L valve springs is a must if you want to safely rev a Hemi that high but until all the tuning perimeters are fully unlocked we are SOL anyway (2011s and up). These 4gen hemi's have good potential but the tranny and the lack of aftermarket performance parts is the only thing stopping us.
Well he has the b&g tune and he said that he can run it well up past 6000
