You make a good - and knowledgeable - case no doubt.
But it doesn't change anything for me. I felt a loss.
The good news is I got my muffler on the other day and I'm gonna borrow my cousins Bully Dog to run some no $h!t 0-60 times with all variations of Superchips Cortex, Bully Dog, Volant CAI, and Stock box w/ K&N drop-in. He's got a Magnaflow Glass pack on his '09 Crew so we're gonna test his with everything too. I'd like to get my hands on an AFE Stage II to throw in the mix but we'll see.
