Im getting an Rtek 1.7 chip installed this week and was upgrading my fuel system to walbro pump, universal FPR, and some higher (720cc) secondary injectors. Im pushing about 12lbs+ of boost on an s5 turbo.

My first question is, with the Rtek chip do i need an SAFC for the car to run well? I've heard they're unreliable and most people just get a standalone system... which would defeat my purspose of getting the Rtek in the first place! But a standalone is out of the question for me at this point..

Second question is, i heard that the stock injectors are good up to 300 horses, so if i just upgrade the fuel pump and FPR do i even NEED the Rtek and injectors?

The car's a daily driver so want to keep it reliable as possible, meaning i dont want to get crazy with upgraded computers and injectors if i dont really have to. (because with my experience, **** always tends to get nappy when you start changing all the components around)

thanks... im a noob when it comes to this kinda stuff

 

or **** would it just be wiser to get walbro pump and a manual boost controller and turn my boost down?

I dont want to get too crazy with the car

if so, anyone recommend a budget minded boost controller?
