What kind of power are people making on 30 overs? I am looking at a CP3 upgrade and a bigger turbo and want to know what the limits will be with the 30 overs that are already in the truck. I know this depends on PW and i am willing to push it a bit. When i build the motor they will be changed out for 100s, but i want to know what i can do for now.

My max effort tune from Kory I'm running 2200us on stock injectors. Do I still have room to go with stock injectors if I do a different turbo?

Not that it is recommended or best practice but there are quite a few 3200-3300 usec race tunes on stock injectors that have lived quite awhile.

2200us is extremely conservative for a "max effort" tune.
Just a bit. My daily driver/econ tune is a 2250 usec at 170MPA. It's not a GOOD econ tune because it is a bit responsive and tough to keep my foot out of it, but by no means a hot tune. Just a good conservative pulse width for a mostly stock engine to keep it clean though. I stopped at 2250 because even there o na hot day it hazes at WOT at 28 pounds of boost on a stock turbo.

Nvm I was confused I'm not sure where I got the 2200 from. I just double checked and I'm right around 2900-3000us. Sounds like I'm maxed out for injectors then. My stock turbo cleans it up amazing and there is no haze.

Thanks guys, I am hoping to hit 700-750ish so sounds like i can get there no problem with a better turbo and pump. Still haven't decided on turbo set up though.
