well I'm getting a DP and resonator delete this week, then hopefully ordering the HV3. And I'll be getting an overkill pcm, because I hear not-good things about zzp's pcm's lol
Nothing wrong with ZZP PCM's.
I got mine for $40 though.
And honestly, why mod a GT? Unless you're going to boost it, pointless beyond belief.. no matter what anyone says.
