It almost seems like the off road pipes didn't help you too much, have you ever considered putting your cats back on for a test? I also recall you mentioning going cat-less enabled to tuning to be more aggressive? Just curious, and what is your thoughts on this? Usually aggressive tuning involves leaning out the A/F ratio, and usually cats like leaner, than richer as far as allowing them to run hot enough and live.
I also commend you on all of your testing/racing, it really helps me and surely others not get wrapped up in spending a lot of money on mods that just simply do much for performance. I'm betting there's hundreds of CAI tune cars out there stuck in the 13's, and then you come along with a closed, stock airbox and rip off mid 11's.
Just fyi, I have a friend with a green 1013 trac pac car that ran an 11.2 @122 with a 640rwhp vortech supercharged mill on slicks and skinnys although his is a manual trans car, but none-the-less, this is very impressive for you and your set-up imo.
I also love that you run 4.10 gears when the rest of the world is saying you shouldn't, either way, mid 11's in such a stock appearing, nice driving stang is nothing short of amazing, and thank you for all of your data.
Too bad my car is a six speed manual, hahahaha. All these killer times with a stall converter makes me want an auto very very badly!!
