hi!
i have a 87 T2 with, stock turbo, 4X550cc,mbc,safc,fcd,walbro255,

so when i turn my boost to 12 lbs i add some fuel with safc

but when it is time for 720cc secondary ?
also what are your safc setting?
talk me about your similar tuning

There are several sites out there that have calculations for figuring the maximum horsepower you can expect for a given size injector. They take into account things like, fuel pressure, air density, boost you are using, etc. Google and see what you can find on it.

yes that a useful tool
but what correction is the best for the safc ?
im using 550cc with a/f gage to set my safc
is it safe? at 12psi

i think the stock 550's are good up to 250hp, i did 220whp on stock 550's and safc and other little mods. i change the secondarys to 800cc now because im upgrading the turbo but i think i could've pushed the stock injectors a little more.
