Updating grounds
We have seen issues with slow cranking for startup and the ability to do a TPS auto set on some of the 2010-2014 Camero equipped with the Gate-Way and Holley EFI.
We have found that improving the grounds by cleaning all the factory ground points down to bare metal, cleaning the ground straps, added a ground wire to the frame and engine block on the passenger side, as well as added another ground strap to the driver’s side block to the frame. This seems to have fixed those issue.
