You're opinion isn't worth much. Do the same research as the OP and come back and refute their findings, otherwise move along and stop vendor bashing.

I'm not vendor bashing and you apparently have no idea what your talking about. The op was right on when he responded about the sharp edges and dead spot caused by removing the Direct Injector. It's evident that the op has done research and good development with the plug. That said, my comments are focused on how the piston is affected when this is done and just what was done to get around the design of the piston. Max Orido failed and it took my team a bit to figure it out, so if the op has been able to run the setup under race conditions without failure I give him all the props in the world and would love to know just why it works.
Factory piston from my ISF
Factory piston from a Fa20 on the left.
The piston designs are very similar. Problem we were having was that after the head work the piston was still getting extremely hot and failing In the same spot that Orido was
I'll exit the thread here because I'm not looking to hurt anyone's business or attack anyone. I'm just interested in how the op got around the issues that come with DI removal.
