I'm quoting myself to show just what I said. Some manufacturers say it's okay to run without a tune. They claim it's safe. Would I run without one? No. Did I tell the OP to run without one? No. Quite the contrary. Maybe I wasn't clear enough in my statement that the sediments of not tuning were that of manufacturers and not me. Note: I have my car tuned to my intake.

I've done my part to save face. Apologies if this wasn't clear. Nonetheless, a 10% increase in lean spots on an already grossly lean OEM tune is not acceptable by any standard.
