Hello,
We have a new 2021 GTR that has been exhibiting some strange problems for the last few weeks. The engine doesn’t seem to want to go past 4000 rpm and power delivery is very jerky. Other than the gas that came with the car it’s only been getting 93 octane from Costco. The dealership did not know what was causing it (no codes). They said they updated the PCM and advised me to drive it to empty and fill up with Shell or Chevron premium which doesn’t sound like much of a solution to me. I’ve uploaded a short video that shows some of the issues. If anybody has any advice related to this problem I’d love to hear it. Thanks! Video: imgur.com
