So what exactly do you need to run Rtek 1.8? If your running the exact injector presets (720cc Primaries & 720cc Secondaries) and a larger fuel pump (In this case the FD pump). What exactly should someone look into getting? At the very least I would think you should need:

* AFR Gauge (To monitor)
* Upgraded Fuel pump
* Upgraded intercooler
* Free flowing exhaust
* Boost Controller

Is this all you would need to run Rtek 1.8? You won't need a SAFC or anything? What amount of boost can you run on a rebuilt S5 turbo ( I assume it's 12psi, but I've heard other's going up to 13psi or 14psi with this setup) with the Rtek 1.8 without leaning out to much.

Is there anything else you should look into getting before running Rtek 1.8? Thank you for your answers.

 

you can just run x4 720 injectors and a larger fuel pump and everything will work.

If you want to fine tune the fuel, then you will need a wideband and a safc.
I wouldnt try and go above 12 psi. Even though the 1.8 retards the timing for you, at 14psi, its chancing it. If I remember, the stock timing map, even with 1 degree of retarding with every psi that the 1.8 does, the timing is still aggressive.

 

with a 1.8 you have to run 4x720cc , or larger, if not running larger then a safc is less necessary..

 

Gotcha, thanks for clearing that up for me

 

Check out Injector Dynamics, I am really happy with the 725/850 setup. I'm still very carefully cranking up the boost on a stock fuel pump and sitting pretty at 10-11 afr on 10 psi with a BNR Stage 4. Max 95% duty cycle and they say to run the most fuel pressure you can with them.
