Does this look like a vacuum leak?

Hey guys,
I finished building my MS (MS2/Extra, pretty much idential to the one in wiki guide). It seems to work. Now I'm in the process of setting up my idle. I disconnected the IAC and adjusted the idle screw until it idles at about 850rpm. That's great.
However, the car starts strangely

It cranks, sits at 500rpm for a few seconds then ramps up to 750, then slowly to 850rpm. Judging by the MAP curve and the fact that my MAP sits at ~40kpa, and vacuum gauge shows ~17psi of vacuum - I'm thinking small vacuum leak.
Here's the datalog: http://s95367906.onlinehome.us/mt.ne...3_19.32.53.msl
It also feels laggy when I rev it (also in the datalog)
