Hi everyone,
I need help with my supercharged (with Whipple) 2019 GT350. I got it recently with the supercharger already installed. I took it to a mechanic for diagnostics and a Lund Racing tune. The car passed the 93 octane tune successfully, but unfortunately, the engine blew out on the E85 tune (rod through block). Luckily, the mechanic's insurance stepped in and covered the engine swap. So, they swapped the engine and moved the supercharger and its components to the new engine. They also applied the 93 octane tune from the old engine.
I took the car back home yesterday, and by the time I got home, the check engine light came on. The mechanic said it's a "tuning thing." I don't really know what's going on, but my guess is that the new engine swap introduced a lot of offsets, making the previous tune no longer suitable. I can't get a proper new tune before I break in the engine. It's showing "system too lean" in two banks and "misfire on startup." Additionally, I've noticed quite strong bucking at RPMs lower than 2k. I don't want to damage the new engine, so I will not drive the car until I have a plan. Maybe the Lund Racing folks can help me with a mild tune for the break-in period, and we can re-tune it later when the engine is ready. Alternatively, I could find a professional in the Chicago area and carefully take the car there for proper treatment.
Thank you for any advice and recommendations.
