Hey fellow Roush owner. I installed a Roush kit on my 2014 a couple of months ago, and it's awesome. JDM has helped me with the tune, but it's friggin' hot in Vegas, and I'm getting some detonation under light throttle when I start up a grade. Once I downshift or add throttle, it disappears.
Curious if you've ever experienced this in TX.
Thanks!
