Ok i've currently got a Safc Neo and concidering the purchace of a Emanage, so far I can see the emanage is better because it has injector timing and ignition timing leads which are optional, from nengun this unit will cost $400 + delivery $100 or so I'd say.. So well worth it. I believe I'll be buying one shortly.
The safc is good, and you can run up to 14psi on a stock turbo without its downfall but 12psi is enough for getting around town. Make sure you regap your plugs to 0.8 when you up the boost because you will hit misfire and the car will feel like its trying to blow up.
If you going to see 250rwkw you will need a bigger turbo, bigger injectors, fuel pump, FMIC, CAI, Aftermarket ECU I.e a Emanage ultimate or Power FC or haltec etc.. And yes get it bolted on and tuned all at once because I losty about $50 a week in fuel compared to a stock car because it ran so rich.
If you going to 250rwkw a step above will need a engine rebuild with forged internals.
So my advice buy a Blue emanage unit, get a new fuel pump, a fmic, boost controller (electronic) If its auto the emanage runs in conjunction with the stock ecu so it will be fine. The emanage is a piggy back as well. Stick under 250rwkw unless you want to spend a great sum of cash on the engine and plan to keep the car awhile. the mods in my sig including an injector upgrade would see excess of 210rwkw on a Neo 34 engine and most likely 200rwkw on the 33 engine.
For example, my sig contains most of my mates mods + injectors and he pulls 191rwkw with no boost mods.
My advice is emanage.
