looking for a little help to get car started. Engine is a 6.0 from a 2011 gmc sierra 2500hd with the matching 6L90E Trans. Had to swap out Ecm to a E38 from a 2009 gmc 2500 that I got from Psi. Also got their wire harness for said engine and a corvette style gas pedal. I was able to get the vats disabled and the engine seemed to start for a split second. Is there anything else that needs to be done or adjusted to just be able to get the engine running? Ive only had the hp tuners for a few days and Ive watched videos on it but they dont seem to tackle my issues. Any help or advice would be greatly appreciated. thanks
