Hey folks,
I have a swapped setup here with a 5.7L engine and supercharger on it. It's running a SD tune. The problem I'm having is very inconsistent fueling between tuning sessions. One day I will get it all dialed in very closely. I will come in the next day and it will be super rich. I will pull a lot of fuel out of it, get things dialed in fine, then the next day it will be really lean. I'm just swinging back and forth and chasing my tail.
I believe that I have all of the dynamic fueling turned off, failed MAF correctly, etc.
Has anyone else ever run into this with SD tunes on the Gen3? Anything in my tune file that stands out as being a problem?
Any help is appreciated.
Thank you!
