Btw the reason I知 asking is bc I知 going to replace injectors any ways
No.
I wouldn稚 get any hp gain or benefit from like getting 24lb injectors compared to stock 19lbs? Bc supposedly with the tune I知 at 300 hp and 344 torque now
Not unless your tuner is tuning for the larger injectors. You use what the tune specifies.
Ah ok thanks
You would lose a lot of power if you just pop them in without any tuning, since they'll be completely out of calibration.
And then once they're tuned for, you'll be making the same exact power since fueling is a fixed ratio to your air intake capacity. Larger injectors will not fuel "more". They'll just fuel the same for the air quantity you have using shorter durations/pulsewidth (once calibrated).
Injector upgrades are only for when you're maxing out the current injectors' capacity. That's not going to happen without major mods.

More fuel doesn’t mean more power. If it did, there would be no need for turbos or superchargers or nitrous, all you’d need to do is just get massive injectors. You need more AIR to make more power. Also, running bigger injectors than what you actually need just gives you less resolution when tuning.
tl;dr
No.
Ok what if I upgraded to n62 84mm throttle body with the ecs kit, stock is 79.5 mm, would that be enough of a change to benefit from bigger injectors with a tune
You can upgrade to bigger injectors + tune at any time you want, but they'll only really be needed if you have forced induction. A throttle body will not make a significant difference in air capacity. So it's up to you what you want to spend money on. Currently it would be a waste.
