I've got around 6500 miles on my car, so I figured it was a good time to finally dyno it today. My GT500 is bone stock except for the SVT intake resonator delete. I went to Pure Automotive Performance in Millersville, MD to use their Dynojet. (Great shop by the way, they have a FR-S with a LS2 in it, so nasty) Their shop is about 15 miles from me and the trip was mostly highway driving. I wanted real world dyno numbers of what my car really makes when driving around normally. No long cool downs or any tricks to get peak numbers. As soon as I rolled up we put the car on the dyno and did two stock pulls. My best run stock was 573HP/579TQ. I then installed a Lund 93 Octane Street tune and did two more pulls. There was about a 10 minute break between the stock runs and Lund tune runs. Just enough time to upload the tune. My best run on the Lund tune was 619HP/628TQ. I'm pretty happy with a 46HP/48TQ pickup and how much it picked up across the entire power band. I'm now "Hellcat Ready"!
