Just something to think about....
Like REDFOCZ said, he logged an AFR hitting pig rich near 10:1 at the upper end due to the COT.
On a N/A engine you DO NOT make good power that rich. You want to be in the 12.5 to 13.0 range.
As far as the cat goes, GM did this to cover their ass on emission warranty issues. Unless you are planning sustained runs at full power upper RPMs the COT ain't gonna help you.
