GTI 6 Inlet Manifold in 1.8

[lewisdmz]

Has anyone had a before and after RR to see how much difference this makes?

Mine will be RR'd at fcs but it's also had other work. Iirc you get two runs at fcs so I might do one with the gti and 1 with the 1.8

That would be a good idea, I imagine you'd need to drive around for a bit with after the switch over though as won't the ECU need to 're-learn' stuff. Or is that another myth?
