07 STI FPR - GR Stumble Mod
I'm sure many of you are familiar with the GR stumble issue and the ongoing opinions on cause/fix. My '10 STI studdered a whole bunch when i went stage 2 and i didnt want to spend the money to replace the fuel system so i decided to to do fuel extenion + fpr mod + tune. Rather than spending $200-$300 on a stumble kit from IAP or Cobb, I bought a 07 FPR and some fuel lines + clamps from o'riellys and only spent 50 bucks total. It's essentially the same thing for minus the fancy clips for a lot less money and to my surprise it removed most of the stumbling and lessened the occurrence of knock.
Well I went back to stock before trading in for the '15 and now have no use for the 07 fuel pressure regulator.
If any one wants it, I'm asking $35 bucks for it.
