How much ET will i pickup with following changes

Just talked to a buddy of mine who is way sharper than me. Thinks this used tranny i bought on here is slipping going into high gear. Need to adjust the bands and try again.
Car was identical to the 60 foot and to the 1/8 mile last night. And the 1/8 mile MPH on all the passes was nearly identical. All just over 94 mph, all 7.20 or 7.21.
