In the preflight setup; everything was uploading properly: route; winds; ATIS; etc. The First Officer entered the expected Runway (05L) and departure in the FMC. We called for our clearance and were cleared via the runway and departure we anticipated. With all doors closed; ready for pushback; we awaited our 'numbers' [Takeoff Performance DATA.]The hard copy of the data appeared on the printer and we waited for the uplink to the FMC; but it did not appear. The First Officer pressed the 'request' prompt for the performance data for Runway 05L (which was the runway already entered in the FMC). We reviewed the hard copy of the [performance data] and the First Officer asked if it was okay to manually enter the data off the paper while we awaited the uplink. I said it was; and he entered the data manually. Flaps 1; no reduction. We pushed back; taxied to and took off Runway 05L. A few minutes after takeoff; an FMS PERF INIT load prompt appeared; and we received a hard copy of [performance data] for RWY 05L. It was; however; for FLAPS 5 and 'Improved Climb.' Huh? We reviewed our original [hard copy printed data] and realized it was for Runway 05R. We took off with the wrong data in the wrong configuration. We later discussed the potential 'worse case' scenarios - particularly at such a critical; high altitude/mountainous airport.
We also discussed how to effectively review the performance data prior to and after loading the FMC to avoid this type of mistake in the future.
When their FMS automatic performance update for takeoff from MMMX failed to appear in a timely fashion; the flight crew of a B737 manually programmed the FMS based on an ACARs hard copy and took off. After successfully departing they received the automatic update and discovered they had taken off on 5L although their manually loaded performance data was for 5R and had utilized flap and power settings inappropriate for their actual takeoff.
