Default 400cc injectors on a 08 HR?? Help

Ok guys almost done before I go get tuned this is my mod list just wondering if 400cc injectors would hurt or help my numbers. I know bigger injectors are usually for FI but wondering if I'd get a tad bit bigger numbers with them anything helps thanks!!!

-3 inch cold air intakes
-longtube headers
-motordyne xyz resonated y pipe
-3 inch single exit straight pipe exhaust with muffler
-stage 2 clutch
-uprev Osiris

I'm going to guess it won't do anything but how close are you to maxing out injector duty cycle?

What shot of nitrous are you running to get 325whp

Also, you don't need and you WILL NOT benefit from larger injectors. . .

^Right. Just keep your stock injectors because you won't see those numbers unless you drop in cams or go nitrous.. With your current mod list you're looking at around 287-292whp at best.

Get it tuned then worry about injectors IF you need to go bigger.

Going bigger for "safety" is just making more work for your tuner.

Your crazy in reality with my mod list i can make up to 315 cause of the 3inch intakes and longtube headers lol pple make 300whp with basic test pipes and stillen longtube intakes it also depends on how healthy your motor is I might buy a meth injection kit any insight on that with n/a vqs?

Strange to ask a question if you already have all the answers.

I have more than just the mods you listed and I'm right at 300. 325 not gonna happen without cams. Sorry.

I’ve seen Saul’s cars and I think you’re going to get 290 Max is my guess.
