    My PE aircharge is modified to account for boost but boost seems to be coming on at low aircharge (~0.58g) and pedal voltage (~0.9V...WOT PE is set to 2.0V). So how do get fueling to kick in when...
  4. PT fueling on manual, forced induction vehicles?

    How are you all handling fueling on boosted, manual cars? The other day I was logging my 2015 5.7 RT and noticed there was quite a bit of timing being pulled but not at WOT but instead at PT. ...

    Calibration details shows it is a 2007 5.7.

    Your WOT pedal threshold setting appears to be factory. Generally this should be set lower ~1.6-2.5V so PE can handle fueling when in boost. Also you...

    Did you try putting the desired startup airflow (ECM 35020) back to stock? In your tune I see startup airflow bumped up after ECT of 50F but colder temps are untouched.
