You can't run a dry shot of nitrous.

FI = Forced Induction (turbo or supercharger).
To do SD tune with FI, you need a MAP sensor that reads boost. The stock one will not.
If you're not running a blower, then SD Tuning can be done with the standard HP Tuners or EFI Live.

I've also heard that you run into problems with a SD tune if you live in a climate that is always changing temps. I for instance live in Michigan, and I just did a whole nine yards to my car with a decent cam (228/236 .612/.580 114+2) and got it dyno tuned and all, but my tuners couldn't fix the bogging/ warm start idle issues. So, i'm considering going SD and believe that will fix my problems...

Flashscan EFILive has a new custom operating system that includes some extra tables that impact on the VE table to maintain an accurate SD tune. One adjusts based on IAT the other from ECT.

So basically, with this new custom OS, there is now absolutely no downside to a SD tune? What are some other factors that could throw off the SD tune? I was also told that you can't do a speed density tune with the stock gm PCM....and I have a 2001 WS6, when I went into a performance shop and asked to have my car SD tuned. So then I ended up paying for a dyno tune/driveability tune where they couldn't tune my car for driveability and then told me it was the cam that I put in and they sent me out the door...did I get ripped?

I run a 23x/24x in my bird, SD tuned. I don't drive it everyday, but I could. Pick up EFILive or HPT and tune it yourself.
