My non-Dinan has no discernible lag. That's the beauty of the "hot-V" turbo set up. My guess is what you're feeling is throttle mapping changes. There's no magic in software. Given the same intake, exhaust and displacement, the pre-boost torque output at a given rpm is the same. Perhaps a bit of tweaking on the cam timing has made some difference, but not as much as simply opening the throttles faster.
BTW Itinj6. I was in NJ last weekend for my nephew's BM. My sister lives near Princeton. Had a blast, but the drive from Newark sucked.
