Hello all I am very new to tuning and I don't know really anything about it so thats why i paid someone! unfortunately, he was unable to finish the tune so here I am with a half-done tune that runs and drives but AFR drops down to 11.9 at idle when stopped, does the same with very light throttle inputs, and when letting off the throttle. I'm experienced with the mechanical portion but a total newb when it comes to tuning or most Hp tuners related things. I have noticed the average injector pulse width does not drop below 1.8ms?? I have tried adding SD AEM AFR/ EQ on the channels, but it never sticks, below are details of the truck.
