I just recently installed a BTR stage 3 cam and LS2 90mm TB to my 2013 ZL1. I have it idling fine but when I drove it for a test drive all three lights for the stabilitrac are one in the Tach and it's short shifting. Also it doesn't appear to be down shifting with more throttle at low speed. I'm not sure if the TB caused this or not. Any help will be greatly appreciated.
