2014+ Boost Level
What boost level can we safely run without having to change injectors or install LT4 pump? Im at 8psi and it's not enough for me.

I saw 10.37 on 1 pull @ 442 hp 471 tq. and its on stock everything. That was when the blower was still relatively cool. He dialed back the timing just a hair after that pull.

What size engine? Stock crank pulley right?
With a 5.3 you need a 2.80" blower pulley for 10psi.
With a 6.0 you need a 2.55" blower pulley for 10psi.
With a 6.2 you need a 2.50" blower pulley for 10psi.
Mulitply by 25.4 to get the pulley in milimeters.
Not sure how small they make them, but a OD crank pulley would help you out a bit.

If it doesn't feel that good maybe something in the tune. I would think it should run pretty good where it is. Take it to the track and see what it mph's. That will tell you something.
