Ryan's 2014 ATS got the treatment to a few parts for testing this week and put down some monster numbers. Our Z57 turbo paired with some ethanol and a bit of Matt Meekhof's tuning magic gave us the world's first 500+whp LTG powered ATS. Be on the lookout for more news surrounding the Z57 in the near future.
Final numbers were 511whp @ 25psi and 493tq @ 29psi on our mustang dyno.
