I have brand new 440cc's and i was going to boost my LS, but had a change of heart and now im going to drop a b18c(gsr) than boost that instead. Now my wastegate is set at .5bar which is 7.25psi with a 57trim t3/t4e I know the ls should make around 220whp, but since im going gsr I know with 7.25psi it should make around 280+. Will the injectors be enough ???

 

you can figure everything out here. You should be fine.
