    Need the Guru's to look this over

    I posted in the gen 3 section by mistake yesterday. I did a drive and log. Let me know what you think. 2010 camaro auto 3800 stall long tubes no cats borla full exhaust cold air intake.

    It has a odd idle i put it in gear it seems to load it pretty hard. It surges at stop lights a bit.

    Thanks all just looking for some help

    You need to add a few more items to the datalog, such as MAF, MAP, and Knock Retard.
    Based on what I see, it's running a little too lean.

    Try some of things I said in your other thread, it's all stuff you will have to play with.

    The open loop EQ ratio should probably resemble something similar to the stock settings but maybe not as rich. It's normally easier for the engine to have a commanded eq ratio that is richer than stoich when it's cold. Instead of an instant 1.00 stoich target when it's 50 degrees.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
