Heres my setup. I have an LS. Stock short block, turbo head gasket, built ls head fully ported & polished, stage 2 cams, and dsm 450 injectors. My turbo kit consist of a Garrett T3/T4 62-1 with P-trim wheel thats been clipped, Tial 40mm wastegate, Tial 50mm BOV. My fuel managment right now is an SAFC and 450cc along with the AVC-R that I havnt installed yet. I was wondering how much boost I could run on these injectors, and also what do you think is the most I can put down on the stock bottm end? I am only running 5psi right now and it spins quit a bit when I throw third so I know this car has potential, I just wanna know how much the stock bottom end can take.

P.S. I am building my other short block now so I really dont care much for this one
