Default Safe with stock injectors?

ive been researching on here to determine if I am going to need to upgrade injectors or not, if so I'd like to do it before I get it tuned, have everything set up and ready. Only issue is I have no clue on my hp number until I bring it in. It's a 98 t/a m6 here are the mods I've done;

SLP CAI/lid/bellow
MSD iridium plugs and 8.5 wires
Pacesetter ceramic coated LT
Tsp Catless ORY
SLP lm2 exhaust
216/220 114 LSA cam /valve springs, chromoly pushrods etc
Unfortunately stock intake (I know I know, saving up trust me)
Double roller timing set
New oil pump and other reliability upgrades.

I've read that if your at or around 400hp to upgrade from the stock 28 lb/hr injectors because they are probably at a max duty cycle or close to it rolling with 400hp. I'm just not sure if those mods will clear 400 or not with a tune??? I've looked at getting some fast 36 lb/hr injectors to be on the safe side, any advice?

You will be fine. Once you get into doing your heads is when you're going to need to upgrade those, but your setup is pretty mild otherwise and you're not going to be anywhere near 400rwhp.

Agree. I had a much more aggressive cam and was tuned with stock injectors just fine. Upgraded when I added heads/intake.

Sweet! Saves me a few bucks for now. I'd hope that 400 mark is within striking distance haha throw some more cash, heads, intake etc and keep chipping away till I get there!

With heads and intake you'd get there. Right now I would say you're probably around 360ish.

Your fine with 28 pound injectors with a good tune until at least 425 rwhp.

My 99 has 26# injectors and they were passable at 418rwhp.

my 00 ws6 maxed out my stock injectors at 380hp with a TSP torquer V2 but i heard the 00 had the worst injectors. i assumed they were all the same. you should be good, if not a set of ford 30# will do the trick and they are cheap too.
