get some 750cc for the primary and you'll be set. There are Rtek7 2.1 setups claiming low 12 sec ~115 mph trap speeds with similar fuel capacity = very respectful HP. My Rtek7 1.8 cycles the 720's @ ~ 5-6% duty cycle @ 900 RPM which equates to over 3 ms pulse width so there's plenty of room for idle adjustments with the 750's.

Not if you're using the 550/720 setting. The difference between 2600cc (2x 550 + 2x 750) and 2540cc (2x 550 + 2x 720) is only 2% additional fuel when the secondaries are active.

Well after some consideration I changed my settings to 550/720. Pulled about 28 - 31 from 2psi to all vaccum. Then used solareons fuel map in boost areas and still had to pull that alot. So far I'm up to 13 psi with a 68.74 duty cycle. Afrs seem to run around mid 11's sometimes hits 10.9. It feels good but I want to hit the 320hp mark. I'm hoping this can be reached at 17psi

Yep. I'm using water injection to try and help prevent any issues up there. I have enough fuel for it. My setup is....
S4 N/A keg with fd oil pressure regulator (otherwise stock)
S4 hybrid, to4b v trim wheel, 38mm wastegate
Fmic, mounted in the spot of the radiator
2.5 dp and mid to 3 cat back
Walbro 255
820cc / 1000cc
400cc water injection pre turbo
Apexi AVCR boost controller
In reading that preturbo injection will move the compressor map up and the right, I hope to still be in the efficiency range at the psi. My goal is 320rwhp. True I may be at that now but I don't have anything to compare it too . If I don't reach that amount by 17psi I'm not going higher but I really would like to see what it's like.
