    New to hptuners, looking for help with 0101 code and tuning

    Just got my tuning software, so please bare with me.
    Car is a 86 Monte , 5.3 running a ls1 intake, lq4 cam, and long tubes. 5 pin maf. Harness was built by Modern Vintage.
    Car cranks, seems to run fine in open loop, closed loop runs rough and throws p0101 code. As stated, new to the whole tuning aspect, hoping someone here can give advice and direction. Not near the car again til Monday, can copy tune log then and post, current tune is a mail order also done by Modern Vintage.

    Log MAF. Maybe increase MAF predicted range and see if it goes away, if not, post tune and log of it when you're able.
