Fuel cut???, Does a 3SGTE need this? Options

[str8thugginit4ya]

Hello fellow 6GC'ers,

I tried searching for the answer to this, but I guess I either am the first person to ask this or I just suck at research. I have a 94 GT with a 3rd gen 3SGTE swap in it. I currently have my boost turned down to about 8lbs. Before I get into the problems I have, I just wanted to know if the 3S needs a fuel cut or not? Also, if it does, is it the 4 wire or 5 wire one? Please let me know as soon as you can. Ok, the reason why I have my boost turned down is because when I have the boost set to stock (14lbs), I get a sputtering, as if the car is struggling to pull whenever the boost hits a little less than 1 bar or higher. Please let me know if this could be because of not having a fuel cut installed or if it could be something else. I already put in new cap, rotor, plugs, wires because I thought it was my ignition system. Any input will be greatly appreciated. Oh, and I also have a AFC Neo hooked up to the car as well if that changes anything.


-Thanks, Ryan

Or it might also be a problem with the fuelling. if at 8lbs boost your engine doesn't struggle n it does for 14lbs of boost...u might not be getting enough fuel pressure. Because if you have enough boost, means that your getting enough air, so air is not the problem. It might then be either the ignition or the fuel or both. As u mentioned, its not ur ignition as u just changed everything to new. Might worth checking your fuel pump (could be too weak for your new engine), your fuel pressure regulator + make sure your fuel filter flows adequately. Or u simply need to clean your injectors? If the problem still persists...make sure your ECU or MAP are ok. Hope i helped.

Thanks a lot. I've been so busy thinking that it might be a boosting problem that I didn't think to check fuel. Don't know if it's the problem for sure, but will check it as soon as I get a chance.
