Injectors

Question what injectors should I step up to, the car is an 05 head cam stick shift with soon to be full bolts ons mamo ported fast and throttle body vararam intake, I'm thinking the stock ls2 injector will be max out? At 485/500 rwhp, thanks for any input

Is is safe to assume that you had a tune performed with the former upgrades and will do the same when you install the additional intake mods? The tuner would be able to tell you if you have maxed out your injectors and what replacements would be preferred.

Ask the tuner who did the first tune what duty
Cycle you were at. If you weren’t close to 90% or so you might be ok.

They will be very close to max duty cycle at that power. I was running 85% at 460 HP with cam + full bolt ons and factory 243 heads. Upgraded injectors when upgraded heads.
