Max boost with no tune

Hey guys I'm not a LSJ guy but I've been shopping around a bit and I'm just wondering, what is the max level of boost you can run (pulley size) before swapping injectors and tuning?

yea u basically HAVE to put in bigger feul injectors if u want a smaller pulley to make a difference. and if u swap EITHER of them, you have to get a tune, or ur **** will probably lose boost!

shoot man, that's annoying, I know the Grand Prix I had at home (ran 8 pounds stock) could go to 12-13 psi without touching anything except maybe the exhaust
