420A Injector size

[Inkdlyfe]

Alright, running out of time, I dont have time for this back and forth tune... what is the biggest straight to the point injector size on a stock ECU fully built stage 2 cams 8.8.1 pistons u name it its done, the tune is just killing me in my area. Car will run on stock Injectors, 255 pump and fpr but will hit 8 lbs on stock injectors. What can I put into the rail to get more power running outta time..

Basically I'm just missing the 4g63 injectors and the fmu, I have a modified rail having a return line back to the tank along with a FPR on the return side of the rail causing the fuel to have to pass that first. I herd somewhere that u can put mustang injectors in ? Is this true ? Oh and I also do have a wally 255 pump too

680cc rochester injectors are about the largest that I would run if you want stock type of starting and idle on a stock ecu, of course you need someway to compensate for the size of them, either a chip or a reflash of a black box ecu.

So I found a set for 75$ but u said it needs a black box or tune I thought this was no tune

 

[motomattx]

Yes those would need a tune, I wasnt sure on whether you wanted something easy to tune or something that would run on a box stock ecu, for box stock the Evo 560cc run good if you use the Evo maf with them.

@motomattx I believe he’s talking about a 420a. In which case, you’d could use a HRC portfueler or a FMU or a mega squirt, or an AEM FIC/EMS. There are other ways I’m sure, but that’s all i can think of now.

Ohh, I didnt catch the NT part of it.

 

[dustyboner]

i think he already has a FIC6

I have a aem fic but I cant seem to get the tune right.. I got it to run but something is wrong. It wont go past 4.5k on the fic but if i take the 880cc injectors out and the fic. It runs perfectly fine. I just need this done asap due to import faceoff is in less then 15 days, so I'm trying to get it running on more boost with no tune

And yes 420a applicant
