Just got my 2012 GT500 dynoed at Performance Dyno in NH. I've got the Steeda Pulley, Cold Air Intake, and a lethal performance off road X pipe and an email tune from Steeda. It made 540 hp and 541 tq. Pete said that the pressure was low today and corrected it made 551HP and 554 TQ. Not bad for a pullied car without cats! Pete said he probably couldn't get any more out of it and that Steeda did pretty well.



Here is the dyno run video

Nice numbers! Do you know what you were before the mods?

Bad azz bro! Did the numbers meet your expectations?

I was hoping for 550 at the wheels. And corrected it made 551, so that's pretty much what I was hoping for. Yesterday was a particularly low pressure day here. I can't complain tho, I mean I drove the car 75 miles to the dyno, let it cool off for about a half hour, then strapped it to the dyno. I think i'm done for now, next mod will be a bigger blower....maybe a TVS from a 2013

TVS from a 13 is a good bet. Takeoff they will be pretty cheap (Even new they are $2k for the blower and elbow, which look like it'll flow way more than even a VMP TVS Kit) and an EASY upgrade for you shelby guys.

And me with the DOB manifold too once I get my bottom end forged
