[QUOTE="2nd2none, post: 11102576, member: 124750"] with just the VMP TVS package and a Roush extreme catback it made 643/665 at about 17#on Justins tune. I added an L&M 72mm throttle body, JLT 127mm big air intake, Bosch 72# injectors, Dynatech longtubes with 2.5" catted X-pipe. Had Justin update the tune and it made something like 681rwhp (I forget the torque). The installer did some datalogging and sent it off to Justin to adjust the tune. It was also suuuuuuper loud with the headers and the Roush Extreme so I put on a set of modified MAC mufflers I got from a vendor on teamshelby.com. We put the new tune on a few days later and it made like 663rwhp but ran pretty messed up. It was really rich down low and the idle was would hunt at times pretty bad.
