Going uphill, you'll progressively run richer. Going downhill might could be a problem--you could get leaner as you go down. So you may need to flip the ignition switch at some point. If you have a nav system you can keep an eye on altitude, or if you have a palm you can watch baro. Only matters if you switch the car off at the top of the hill.

That's why I paid the extra $$ for MAPdaddy

To fix it... u can get another 2.5bar sensor and solder it in upside down above the other sensor... leaving it open to the air... boom... barometric correction.

So basically at some point I'll need to redo my fuel map when going up and then redo it again when going down?

Turn ign. off and then turn ign. back on after a few sec. I recommend not doing this while still in motion on the dragon haha.

MS takes an atmospheric reading before it starts.
