Can anyone tell me why ever since I had my truck tuned I get this code p 01 02 airflow signal voltage low? Been like this since it's been tuned never had this problem before not even with my twins and stock tunning ?
Right now I'm running stock injectors how big of a difference between the 83 and 87? I'm running a Suncoast 1058 converter I don't want a great big lagging pig haha is spool up gonna be a huge problem between the 83 and 87?
