Where we live the weather is different all the time so if it has an sd tune its not going to be making the most power that it can when the weather conditions arnt perfect.

Im not quite sure why the sarcasum but its whatever....with and SD tune its tuned to one certin condition witch is whatever the weather is when you are tuning the car. Also most of the tuners in our area prefer maf tuning not SD...Im not saying its bad or one is better than the other its just a personal preference.

Also, my car does have both an IAT and MAP sensor, so it can actually read the weather conditions out there that matter most and the tune itself can accommodate for changes in such both at WOT and part throttle.
Now it might not be adequate at making changes if the altitude changes (which I don't forsee myself going anywhere past 1000ft. above sea level anytime soon) but besides that the tune can compensate just fine for temperature and humidity changes in the weather conditions.
So what other weather conditions is my SD tune not able to compensate for?
And I think most tuners prefer MAF tuning over SD because of simplicity and ease of tuning, not because it's that much smoother and reliable than SD.
+1 for SD tuning. Although I don't see a need for it in this application. Your stock MAF will not pose a noticable restriction. Typically I'll use it on big cammed NA cars where lots of overlap can cause the MAF to read irratic at idle and just off idle as the MAF does best with non-turbulant flow. That and FI applications where the MAF is maxed out. I've been running SD for years and do not see my AFR or fuel trims swing due to weather. Only a drastic altitude channge would require a change to the tune.
