I would call on this but i know they are moving so i thought i would ask here. When do all of you turn it from stock to which ever setting you usual run on.In the diretions Jody says to change it after the engine is warmed up,but i got to thinking about the PCM burns he does and thoses are on when the the truck starts.So i got to thinking(which i do alot of) that maybe i could change it as soon as i started it up. Just wanted some opinions on this.

Over a year and a half with mine and I almost always start driving right away in 80 econo. I never had a stock setting until recently when Jody reburned my chip, but I don't use it anyway. Only on the very coldest days I would put the chip on the 40 tow setting. The reason is just because the injectors were super noisy in sub-zero temps, and usually there's snow on the ground at the same time, which makes driving a bit squirrelly with extra power.
Nah mine are noisy in sub-zero temps no matter what tune it's in. Every other PSD up here that I've heard sounds just like mine when the weather is like that. It's only slightly less of a knock in the 40 tow setting compared to the 80 econo. Mostly I switch it over because of traction issues, not noise. But I guess part of me also changes the tune because I'm paranoid.

I never noticed any problems with the injectors. They all contribute nicely according to AE with almost 100K on the ticker.
