Default Need some advice on injectors

currently im running s2/s3 hybrid with no other fuel modifications. Im running out of fuel at a 21psi spike and 18psi hold at a 12.5 AFR. Walboro 255 is a must.

Should i ditch the s2 injectors and roll with 750's or is that over kill? or just get an AGP returnline? if i ditch the s2 injectors and get the 750's ill have to get a flash or something to compensate for the extra fuel. Returnline just seems like it would be the easier less expensive way but is it enough fuel?

I wanna be around a 25psi spike and 20+psi hold.

The 12.5 is at around 5800 rpms other than that it's around 11.5-11.8.
