Good day all,
Question here is why a tuner would change just injector flow rate for FIC 127#'s? All other injector data is stock.
Even these numbers are not what they provide.
Long story short is, when the aux pump kicks on, there is a stumble// hesitation@2500 rpm. Dave with DSX says if there is correct injector data, there should be no problem.
