Some knock under sudden changes in engine load like that aren't totally uncommon. I can see a couple of degrees of knock just putting around town. For instance, 45mph, 5th gear, floor it.... you'll see plenty till the engine gets spinning a bit..
1.3 under full load, boost, and rpms, isn't too bad... although, with your mods, I can't imagine you should see any. Under normal conditions. I never see any, and engine wise, it looks the same...
