any1 running 550s with a afc?

[zeause]

I have a s14 blacktop that i rebuilt and im guna be running 550s on it. I have a gt28rs and a 300zx maf, but i have to drive it 500 miles to break it in and i was wondering if anyone else is running this set up. I was wondering if it would run fine with all the settings on the neo at 0 or do i need to adjust it to run with the 550s? Thanks, Casey.

I've got a notch top with 550's untuned and it won't even stay idling unless I reverse the fuel lines. You need something to tell the ecu what to do with those injectors.

All i want to run is about 350 to the wheels, An afc is more than efficient to do this. So thanks for no help at all smart ***.

no matter what you decide to do you are going to have to tune.

The suggestion to throw your AFC away is very common as it is NOT a reliable option for tuning when you are talking about Control system mods (injectors, MAF, Ignition). If you want to run 350whp you need to get a good ECU tune and maybe use the AFC for back up and fine tuning, but most people that try to get good tunes out of the AFC usually find themselves frustrated and dissatisfied with their performance.
