GTI for sure. The stage 1 on the WRX really just fixes the factory tune and doesn't add much power. The boost levels are stock and more linear. So no added boost at all for a stage 1 on the WRX.
Stage 2 WRX vs stage 1 GTI would be a better comparison.
However, the GTI definitely had traction and wheel hop issues at stage 1. Both issues I won't have with the WRX when it gets to stage 2 which is really just adding a J-pipe (downpipe).
I'm not power hungry, but I like having a car that goes when I need to pass someone.
I'm pretty sure the GTI was also lighter.
