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.
I understand what you're saying, but I can actually feel when the turbos spool up enough to get a boost before and after the tune. It's definitely more prominent with the tune though. I would say it's a combination of the things you mention above and not just increased boost. I may be wrong, but I'm going by feel. You just tap on the gas now and the car goes. The pedal feels very sensitive now as well. Before, I felt like it needed more effort to get it going.

Did you take I-95? It's usually free flowing. Congrats to your nephew for becoming a man... Mazel Tov!

On a side note, I just had H&R Lowering Springs installed and some coding done. I feel like I lost my Dinan Tune. I called the dealership that installed the tune and they said they will check it out. I have an appointment for that on Monday. Hopefully it does actually need a re-flash and its not me getting used to it lol. I'm sure it feels stock again though. Dinan specialist at the dealership said it's possible they did something with the electronics when they installed the springs.
