Surging Idle First start with blower??

So I finally got a base tune from eric brooks today, started the car up and it started surging between 1-2k rpms, while the AFR was around 14-15, then the AFR richened up to 10 and the idle smoothed out, and the Vacuum was at around 10 when smoothed out and idled super rich, anyone have any idea what could be up? Does it sound like a vacuum leak?

Check for vacuum leaks, but it's a base (start-up) tune so it's not going to be perfect. Cruising/Idle should be in the 14-15 range, don't go WOT but that should be in the 11.2-11.6 range.

Sounds like a typical base tune to me to be honest I wouldn't worry about it until you get to the tuner. Just don't be getting all over it and youll be fine.

Idk the car wont keep a steady idle now, and the vacuum bounces below 10 even, also the thing is I'm doing a remote tune, so this is supposed to be the idle tune and a tune i can drive around with, but I can't, it just surges, heres a video of it
