Direct injection ???

In one area you sell the tool and plug and say it will work up to 2018, but in another area you say The VLOM plug will not work with 2018+ DFM equipped vehicles.

ive installed a plug in a 2014......it does block the vlom and allows oil pressure to sensor....is this going to cause other issues????

I will be clarifying that part of the sight soon. You and I had a PM on the topic but for forum sake I will add how I explained it to you here below.

DFM is not for direct injection. It stands for direct fuel management unlike AFM which stands for active fuel management. The difference in operation is what matters. DFM controls the system to make 2/4/6/8 cylinder operation possible. AFM controls only 4/8 cylinder mode. AFM was used from 2005-2017 possibly some early 2018. After that they went to DFM which controls a variety of cylinder options and no longer has a VLOM.
