Email tune (VMP Tune) was in the car when i purchased the car a few weeks ago. Added an o/r xpipe and CJ 65mm and went to my tuner to have a dyno tune done. After making changes for the xpipe we did a baseline and it made 604. After dyno tune she made 667, pretty cool how much extra you can pull out of a car on the dyno compared to the email tunes.
Enjoy!
