Thanks for all the advice
Iv never seen a 25 or 35 shot dose it even do anything,and another thing I have 550 rc .My plan was to hav the vafc lean out those.
But if u guys think a 35 shot is safe then I won't go past that

you just through off the whole main point of this with the 550 rc injectors. do you have a wideband installed in your car?

my personal opinion would be that isnt a good idea. if you want to run a dry shot get a fuel pressure reguator and a walbro 255 fuel pump and use a vafc2 to trim fuel off until you spray. i dont know how well that would work but it is an idea. but you will run rich when you normally drive in higher rpms

The aftermarket injectors really change the whole game. I think the VAFC is going to be a nightmare for you, since it is only good for leaning out fuel at wide open throttle. You might be able to make it work in your case, but it's a long shot. Honestly, I'm surprised your car even runs with 550 injectors and a stock ECU ...
