I have a 2009 crew cab 5.3 planning on installing stage 2 turbo cam, head studs, ls9 head gaskets, dod delete, and a Bourg warner s366 turbo 600 rwp will be my goal. what fuel system upgrades would you all recommend. Most likely will be running 93 octane but there are some gas stations starting to sell e85 so thats a maybe in the future.

 

If youre ff your pump will get ya close to 600...with said run 93 call it a day

Buy injectors and drive it

 

Stock pump? What injector ?

 

if youre truck is flex fuel your pump will be fine

injector 60s 80s 96s up to you

 

Hate to sound like an idiot because I've worked on ls engines for a long time but was mainly f bodies this truck has all badges removed how do I verify if it's flex fuel
