I have vortech supercharger boosting 10 pounds but want to bump that up. I was wondering what yall think would be the most I could boost on a 5.3 safely.

2004 5.3l, Vortech sc, #43 injectors, level 4 FLT 4l60E, Yank 3200 stall, magnaflow exhaust,K&N CAI, Tuned by LG Motorsports, 2/4 Drop, and 20" Chip foose rims.
I believe 12-14 psi is about max on stock bottom end. You will most likely need bigger injectors (unless you have some duty room left on your 43's)
Not sure what your IATs look like, but if you aren't IC'd...that might be first place to start.
blown transmissions are about as useful as 97% of the guys on this forum
Make sure you get re-tune and watch your a/f.
U need more injector for sure.... and 10psi will take you a ways... I know a pulley change seems easy and cheap and boost is great but.... why not install a custom cam/springs?? thank will be a good 60+hp gain... what type of air fuel and timing are you currently running?
