I've always limited VTC mechanically based on high cam clearances and I know that is what is recommended for most to ...

So would there be any negative performance results observed if removing the bypass when using stock injectors?
Performance, no. Unnecessary work, poorer emissions and fuel accumulating between the intake and head, yes.
Thanks for the info! I was just checking if it is cool for those with K swaps ...
