Your truck a flex fuel? If so stock pump works fine on a 5.3 at that boost level. Just remember in the tune or at least on hp tuners there one page that commands 14afr for some wierd reason giving the idea that your pump is not keeping up. I'm still running my stock flex fuel pump on my 427lsx with a 106 on 10lbs so stock will be plenty for your setup.

This is a part that cost roughly $100-150 why risk a $5000 motor over such a small part? Also need to focus on power level not boost level. A certain 5.3 on 10psi may make more power than a 5.7 or 6.0 on 10lbs. I am certain that you know fuel need is based more on power than boost level.

I'll have to check I don't know off the top of my head... And yeah I know fuel is dependent on power but I'm just saying that stock pump is ment to last 100k+ miles and if it's sufficient why worry about it. Every setup and part is different so hard to speek for anything else other then my truck and my truck has zero problems even on 10lbs... Wideband is 10.5 all day right now. Do t get me wrong I'm all for overkill and would always say put a better pump in but for 10lbs in a little 5.3 weather you have a big cam or high flow heads I would say think your pretty safe with a stock flex fuel pump.

FF pumps are the upgrade for some of the blower kits out there
you can make 500rwhp with the stock FF pump and have a reliable pump that is factory vs others
the new FPCM dont always agree with other pumps on the market, its not like the GMT800 trucks
