Correct. Power remained the same too.

yes.

What did they do to keep the power the same, you can clearly see the power hump on my dyno chart where the vvt comes in

I had the VVT tweaked in my NA to 500rpm lower and it makes a big difference :D

Its within the ECU Chip remap. John dixon changes the VVT point on his Chips, I imagine the others probably do too.
