I guessing it's N/A ? If so you only need a little more than stock.
Just putting yellows into p1 (giving you 6 yellows) would be sufficient.

6 yellows into p1? I thought the yellows were less cc? And when you say p1 is that the secondary spots?

Stock is 2x reds in P1, 2x outer yellows are the secondaries and the 2x inner yellows are in P2.
Yellows flow more than reds

OH, so just using yellows will be suffice without it hitting its limit? Im in an automatic so my rpms wont be as high but still worry, im also streetported and use nitrous

Also unrelated note im a huge fan of your work like the electric turbo was genius and ive seen some of your stuff on facebook too and i almost always end up reading your threads when im confused

Yes 6 yellows will suffice. You may even get away with stock injectors if it's an auto with 6 injectors .... I'd try that first.

To achieve balanced fueling, it is recommended that you use six matching injectors, choosing a size between 800cc and 1000cc.

P1 and P2 share the same port so to get 'balanced' fueling you would need those to be 1/2 the size of the secondaries.
