06 2500ccsb tuned with duramax tuners efi live. Lifted 8" . The truck idles normal in park when I put it in gear the turbo vanes go to 70% and I have to stand on the brake to keep it from moving. In reverse I let off brake just a little and it starts spinning tires. Cts2 says throttle position is 0%. Replaced vane position sensor due to code and that didn't fix the problem
