MO some questions on my rtek 1.5

Build as follows
1988 rx7 Se converted turbo 2
S4 engine and Stock internals
Rtek 1.5 bought for when it was stock. Decided to upgrade engine
Safc to tune with
innovate wideband
Front mount
53mm hybrid turbo ported waste gate holds 9 psi with stock waste gate
800cc primaries
1200cc secondaries just installed today.
Didn't go so well on the first run. I just want someone to confirm the 1.5 is not gonna work for my setup. It hit 3500 and fell on its face. I'm assuming the transition isn't going to work. I upgraded to 1200s Bc I had 800 primaries and 800 secondaries still leaned out. I want to run 15 psi so I jumped up to 1200s Im Assuming Rtek 2.1 is next on the list. Give me some ideas on where I should go next.
Thanks for looking.

1.5 is for stock 550cc injectors. Ditch the AFC and get 2.1.

Yes I am very aware the 1.5 is for stock injectors. I was trying to make it work without dropping 500 bucks on a 2.1 it was tuning 4 800s just fine just leaned out when I upped the boost.
