I've been waiting for your other shoe to drop by way of explaining to others why it's wrong. If so, please say why. We fly 800s with the package and I can't find anything in the FCTM, the FCOM or the QRH performance section except data on the pitch-roll angles at which various extremities of the airframe are at risk or not depending upon whether an SFP package is installed.
The only information I am able to find online is from non-Boeing sites which in itself points to another issue regarding getting information for operators from Boeing, but I'll leave that aside.
Here is what B737.org has to say, as linked to previously:
The Short Field Performance improvement package was developed in 2005/6 to allow GOL airlines to operate their 737-800s into the 1,465m (4,800ft) Santos Dumont airport. The modifications enable weight increases of approx 4,700kg (10,000lbs) for landing and 1,700kg (3,750lbs) for take-off from short runways. It includes the following changes:
- Flight spoilers are capable of 60 degree deflection on touchdown by addition of increased stroke actuators. This compares to the current 33/38 degrees and reduces stopping distances by improving braking capability.
- Slats are sealed for take-off to flap position 15 (compared to the current 10) to allow the wing to generate more lift at lower rotation angles.
- Slats only travel to Full Ext when TE flaps are beyond 25 (compared to the current 5). Autoslat function available from flap 1 to 25.
- Flap load relief function active from flap 10 or greater.
- Two-position tailskid that extends an extra 127mm (5ins) for landing protection. This allows greater angles of attack to be safely flown thereby reducing Vref and hence landing distance.
- Main gear camber (splay) reduced by 1 degree to increase uniformity of braking across all MLG tyres.
- Reduction of engine idle-thrust delay time from 5s to 2s to shorten landing roll.
- FMC & FCC software revisions.
