Hi Rob, I have a 98vvc with rolling road of 130 only. Am I correct in understanding this is a detuned motor of the 160performing variety. Mine has a 1.9j ECU and I'm contemplating a plug and play addition to uncover some extra hp. I have a 52mm TB, a forced cold air filter setup, a hiflow cat =200, and a Phoenix exhaust. It breathes very well and despite only 130 on rolling road it accelerates well and revs freely. Any thoughts?
