These are the same numbers for the GTI, but since it's still the 2.0 TSI in the Beetle, you're right there too. Stage 1 is all about the low-end torque, so you're really not gonna feel too much more after 3rd gear (assuming it's the same in the Beetle as it is in the GTI).
Now, I actually checked GIAC for numbers (since I don't know what they put out), but they have no product specifically for the new Beetles....which doesn't really make sense why they wouldn't since it's still the 2.0 TSI. I'd put down the numbers for their GTI software, but if there's no part # for their product on the beetle, I guess there's no point? Still checking into it
Also, another thing to note about the mk6 is the clutch. It kinda sucks lol If you go anything past Stage 1, I would look into some aftermarket clutch kits. Mine has held up pretty well under Stage 1 power, but these things have a knack for going out right after Stage 2. It's best to be prepared for that if you have plans to go past Stage 1.
