No.
Actually cold start is leanish in this car, warm start too a little And it's actually in open loop state when you first start it cold If you measure AFR with a wideband with a stock tune, you ll see subaru afr stuck around 14.7/15.16 (it has various level undefined to me) Meanwhile the wideband measures even slightly leaner The pops are from stratified and retarded DI injection and negative ignition timing, combined with the timing retard induced by the throttle blipping, both pushing it and releasing it There are also other OEM tables that limit the amount of retard while coolant is cold and while clutch is pressed (ever noticed sound changes when you press clutch to go in reverse during cold start?) and while it's complicated to see how and when those tables act, the burbles you get are mostly from retarded ignition timings |

Sorry I wasn't clear on what part of his comment I was addressing.
Yes all you said is accurate and when you add sudden fuel to those conditions you get more pops than normal.
