    Opinion on this tune, is my car running lean?

    Hello

    When i had installed long tube headers (TSP 1 7/8 with catless x-pipe) on my Corvette c7 (2014 LT1 engine) i had my car remotley tuned by a shop.

    Alot of people that have seen my tune told me that my car is running lean.

    tune in attached, any opinions?

    thanks,

    Alessio

    Without a log file with wideband data we don't really know if it running lean or not.

    The commanded fueling under heavy load is not set to be lean, it's technically a tad rich for a direct injected engine. But again it may be asking for that and not actually seeing that in the tail pipe.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
