Hey guys truck is runnin very strong. However, I would like to take full advantage of the 71mm. Right now I'm runnin 38 psi thanks to Brayden. Fleece has been a great shop to deal with btw. From what I've been reading most like to run around 42 psi. My question is, can I do it with stock injectors. I've been told yes and no. Would like to hear some more thoughts. I do know drive pressure plays a big role in this. Getting one of those soon.

yea, I ran 40-42 all the time as a single, I run 50-52 now with it on my twin setup :D Just remember to get your vane position opened up a bunch at wot and you dont need the vanes so much closed down as they probably are right now in the acceleration/cruising parts of the vane tables, stock vane settings are not needed.

I run 39psi after I got injectors. Before that, I was running 39+ for boost. I know that afterwords I was a lot more efficient with boost though. Injectors will make you smile.
