Full Throttle Shift

Long story short, i have a b18 with a 6765 on e85. pretty well dialed in at WOT and running damn strong (went 8.89 at 123 in the 1000), but i am having trouble keeping my boost up on shifts. it is not a shift speed issue, its a spool issue. peak boost is around 24psi and on the shift it is falling to 18psi or so for longer than i would like, then it builds back up to the peak boost (obviously). In all honesty, the full throttle shift parameters are a little intimidating and im looking for advice on how this should be correctly setup from people with experience with it on some drag cars. Also, for those that are, do you believe this would be beneficial in maintaining boost better on the shifts?

its pretty easy to understand and set, record your shifting for say 1/2 2/3 3/4, find the rpm you normally end at, say shift at 8k and it drops to 6500k then set your full throttle shift rpm at 6700k and give it a shot. you can lower or raise it as needed for your shift patterns and preference. dont worry if you set it higher for first say you set it at 7k but normally land at 6600k the extra 400rpms will not hurt anything.
