Hey guys, I'm collecting some parts to boost my 2003 Silverado and I have a few questions. I bought a Huron Speed T6 kit and was making a list of other things I need and wanted some input on the things I need or if I am missing anything. The truck has a 5.3 with 241 heads, TBSS intake, and a summit 8709R1 cam. It's also got a t56 magnum and 4.56 gears.
So far I have:
Huron Speed T6 kit with a VSRacing S480 AERO T6 1.32 Race Cover Turbo
Huron Speed HS60v2 wastegate
Huron Speed HS50v2 BOV
The kit comes with the hot side, cold side and pretty much everything to plumb it.
I need injectors and was wondering if these would work with the TBSS intake and fuel rails? Injector Connection Injectors
I was going to buy the Huron Speed fuel pump assembly with the wiring harness but only run 1 walbro 450 for right now until I need another pump. I don't exactly have any power goals... But I would like a decently fast truck. ( I know that's subjective)
Will my stock fuel lines work? Do I need to upgrade to -8 feed -6 return right away?
What are you guys running for boost referenced fuel pressure regulators? I was thinking this one unless someone has a different brand that's better for whatever reason? Aeromotive Fuel Pressure Regulator
I've read people us the cobalt SS MAP sensor. Would this be the one?
I know I'll need a muffler and some tubing but I can figure out what I want for that later. Am I missing anything you guys can think of? Also if anyone has suggestions for better parts or something that would work better for me, please let me know!
Thanks in advance!

2003 GM truck fuel rails come stock with a boost referenced fuel pressure regulator.
I have two stock regulators working well under boost, they both reliably track 1:1
Damn sharp looking truck.
Put some PRESSURE to it and it's gonna FLY.
Only one thing, you will find first gear USELESS with the 4.56 rear axle, gonna melt tires bad in lower gears.
My bad guys I just got busy with some other projects and customer cars.
I'm still in the parts gathering stage but I'm hoping to start on the truck in Jan.
I recently got huron's dual pump module with 2 450s and thier fuel rails. I also got fic 1000cc injectors.
I still need a fuel pressure reg, map sensor, fuel lines and fittings, boost controller and a boost gauge. I pretty much know what I need except the map sensor so if you guys can recommend something that would be cool! I saw on3 sells one but I'm a little leery about it
We can't get e85 for some reason here in AZ so I'll have to stick with 91 and maybe some methanol.
