I searched and read up about this topic and I know that others have pulled off using an Apexi SAFC II or Neo for their SCd GS4s. However, I just want to make sure that this is still safe for the engine to go this route. I am NOT looking to spend more money and I understand you gotta pay to play but you gotta draw the line somewhere sometimes. I will be using an Apexi Neo as well as an Aeromotive electronic FMU to manage fuel delivery at respective boost levels. I will only be at 7lbs max at around 400whp with 440cc injectors. Will I be OK tuning and maintaining proper AFRs with the Neo?

 

Like I said in the other thread it will work but safe? No it's a bandage tune by tps is far from safe but will work until something goes wrong like a tps going bad etc etc

 

I would do Greddy Emanage Ultimate or AEM FIC8 at the minimum. Don't skimp now on the management

 

So, obviously with either of these units i'm looking at another $600 bill plus an additional $250 for a PnP harness from Boomslang as I do not want to hack ecu wires, is this correct? What a PITA. I will also lose the interface capability of the NEO such as seeing battery voltage and other items; if I'm not mistaken, I believe the Greddy and AEM are just piggybacks that sit under the hood.

 

All of them are piggybacks so to speak but the AEM is about as good as it can get with the stock ecu but 600 is a lt cheaper than a new engine the afc is by war the worst choice for tuning and any reputable tuner will back that up.
