GFB Respons Setup on a 2.5T

Postby SuperS0nic » Sat Nov 13, 2021 2:13 pm

Has anyone got a sure-fire way or tutorial on setting up a GFB Respons correctly on a stock tune? I've seen the GFB video on the gen 2 WRX but I am wanting something a bit more specific to our cars. My car also has the Genome rear mufflers which even with the stock BPV makes a bit of exhaust popping vs the stock mufflers so I don't really know how much is too much.

For bp/bl GT, gh wrx or sh Xt, all with the ej255.

What’s your popping issue with the genomes? Is it on boost?

I’d recommend getting a Btssm or Romraider setup so you can monitor your state of tune with the mods.
