There is a guy here in norcal that has them deleted on both of his cars and hasn't run into any problems. He doesn't have a way of datalogging either, but the whole concept still makes me nervous.
The concept works...it has for me. It ain't rocket science
You just have to have faith, and a lot of patience.

He has no "current" way of datalogging. Originally he did to get the car dialed in. His tuner is very good and I'm sure it was tuned very well. He just has no way to monitor it now.
Oh, okay...I see what he's saying. I don't monitor mine on a daily basis either, but once you get it close, our PCMs are robust enough in SD mode to not sway much at all on a day-to-day basis. Honestly, I found my tune swayed more with the narrow band O2s still in operation due to their shitty operation. It sucks when you watch one flatline completely, and the car just dumps tons of fuel in to compensate.
