I'm trying to create an SD mode tune I can try on my L31 5.7l mild cam daily driver.

I've done a little study on this and obviously haven't looked in the right place yet.

I just had an issue and had to remove the air bridge, when I got everything buttoned back up, I forgot to plug in the MAF and IAT . I immediately noticed better throttle response when cold and thought it might be something I want to try in a little more complete way.

Any thoughts?
