Another Dead Battery - Computer Reset Question

Yep, left my Boxster alone for too long and discovered the battery had died. Thanks to this forum I was able to get to the battery and start charging it.

Question: After recharging the battery and getting the car started and running again, I noticed that on full throttle the car surges and slows, while the engine is still revving towards redline. Seems like the computer is retarding the ignition or something. When I go to 3/4 throtle, it starts to pull hard like normal....well, normal for 3/4 throttle.

Is this due to the computer losing some info? Any way I can reset this? Or is this something a shop using OE software has to plug in and program?

The only other issue is a problem with the secondary air injection system...only during cold starts, CEL codes (I lost my OBDC scanner) the ususal O2 sensor error. It could be any part of that circuit though. In the past I've reset the code when the engine is warmed up and noticed no difference in acceleration.

Any help is greatly appreciated.
