Hi, I'm new at FAST and I installed my first FAST XFI Kit a couple a months ago in a GEN III 426 HEMI. After read all the available documentation and make a lot of adjustments, I got the engine idleing. My problem is even when the ACTUAL A/F ratio is stucked at 15.94 when the engine is idleing, it's smells too reach. When I accelerate the ACTUAL A/F changes. Any clue? PD. Sorry for my english, I'm from Argentina.
