I have a 2017 ZL1 A10 on the dyno. The car had normal baseline dyno numbers of 554/546 sae. I installed a package that we have used on many 2015/2016 Z06 A8 cars. 15% lower, Kooks Headers, Rotofab, thermostat and plugs. On all the Z06 cars I have equipped with this package I am in the 660/680 sae range and have four cars equipped with this package in the 9.70/9.80 1/4 mile range at the track. I have never done a 2017 Z06 or ZL1, so this could be a problem on my part but no matter what I do the car makes no power. I have almost 25 dyno pulls on this thing and I am in the 550/600 sae range. My highest is one run at 587/592, just once. I have no throttle issues, full 12.5 psi boost, 12.4 AFR, I have been 11.8 to 12.8 no difference and full timing with no torque management. Around 4k rpms I do pickup spark knock. I have logged everything and it appears to be real knock picked up on every cylinder. I have added Torco, little help removing it and played with knock sensitivity. I even removed all retard from the system and still made no change in power. I see lots of people on the internet working on 17 tuning issues but nothing has come of them. Any one have any ideas.
