Like he said, Each tuner has their preference on injectors and I don't think driving it to get tuned would be bad if your tuner sent you a detuned map to limp there on.

just don't boost over stock, you should be fine...
i still remember the days of pulling plugs after a full throttle run to check the color to get my estimated af ratio. you guys are so spoiled

You will also need a new pump if you don't have one, will you be tuning on 91 e85 or race gas. I would go between 700 -1000cc injectors. And no I would not drive it!

Thanks for the help yea I figured 700-1000
I'm just wondering if it's ok with my Sti pinks if I don't boost past like 10-12 psi
And I'll be using 91 or higher. And yea I already got a Walbro installed

So the stock Sti injectors on the stock Sti turbo are pushed to the Max? That doesn't make sense at all to me but ok

I dont know about that... Because I've seen guys get way better numbers out of a 20g, e85, and 850 injectors compared to being tuned on the stock turbo, and injectors.

Thats what I'm talking about.... The duty cycle. He won't be able to run E85 on the stockers.

I also suggest you talk to your tuner about the size of injectors to get and whether or not you can drive your car without a proper map. If you ask me though, I would say at least 750cc injectors and don't drive the car.

I'm pretty sure azer408 meant a VF turbo will max out STi Pink injectors and the Pinks will not be able to support the 20G.
