Hi- New to the forum, and i have picked up a 80,000 mile 2011 cruze with the 1.4L. Always maintained. I put a cold air intake on it and just 2 weeks ago the Trifecta Tune. Everything was running great and then the check engine light came on with the P0299 code, "under boost". I didn't notice any sort of running issue or any difference at all.. The code being thrown just worried me. I cleared the code and put the engine back to stock. Did the tune cause this? I would really love to run this tune since I see good improvement with it. I also run the 91 octane fuel. Whats everyone think? Thank you!!!
