I got to agree Ktoom119,
I'm thinking I don't need the Cats with the SAS removed. I also think someone wrote in the TuneECU thread that shutting off the O2 sensors would/could ruin the cats. That is something that has helped some riders in their tuning, also in the thread.
I'm just a little leary removing stuff because one of my riding partners has Acraprovics and map but still has the SAS and riding behind him smells like lots of unburned oil and gas is getting by and it stinks (07 990S). Around here it's death to the contaminators.
