What is your duty cycle ?? I have been told when you exceed 80% at WOT you may consider upgrading unless we're only talking about a few % points over 80. I am sure someone much more in the know will respond to this and help you further. Good luck.

I would imagine its definitely time for some bigger injectors.. mine is close to 80% DC with the small mods in my sig.. lol

With my cam, the duty cycle was at 98% at only 6000rpms. Had the shop put in 42lb injectors.
I would say yes to getting bigger injectors.

BOSCH 30lbers will be fine. 42's would be better if your upgrading in the future. My 42's were at 98% duty cycle....and they can go higher, just watch the AF ratio. Not recommended but,...doable. Seen 30lbers on 600rwhp cars and 900 on spray.

I'd buy 38-40's if these are the end of your mods.

...and I like the SEIMENS brand injectors....as they are probably a better TUNING injector.
