Default dsm 550's management?

Alright guys i have a stock b16a2 that i'm boosting plan on 6-9psi i ordered a set of 450cc injectors but received 550's .. oh well.. anyway everythings almost done BUT i don't have fuel management yet.. i'm going to be running a p28 ecu too so would a basic v-afc work? or uberchip? feedback would be great

I believe the 3000 GT or stealth had 550 cc injectors on the twin turbo models.

The AFC hack MAY work but you're going to still run extremely rich through out the power band.
Just be safe, upgrade your MAP sensor, and chip your ECU along with this.

I don't want to give exact advise as to what to do...

But your AFC can only lean signal by -50%. With 450cc injectors at about -38% you're running close to factory flow rate. I am guessing you could probably use the 550s, you'd just have to have like -50% at idle, and probably go up slightly across the band.
If you get it to work you'll be able to run even more boost then with the 450 hack! But I think you should probably upgrade that MAP sensor just incase you do use higher boost levels and cause some spikes.
I don't know what ECU chip to use, Joseph Davis would be the one to suggest it I imagine.

Seems to me like the AFC Hack will work, just not as well as with the 550s, ie you're going to run really really really really rich if you ever rev it in neutral... which is okay, just dont make a habit of it and on cold mornings lean it out as much as possible at idle.
(fireballs possibly!)

AFC would work.

Uberchip's tuner would calibrate them perfectly.

I'd rather have 550's than 450's... you're not in any trouble, trust me
