I have an Apexi AVC-R, the unit in the picture above.
There are no other parts, just the box, lead and plug.
Would this item be useful as part of the supporting mods for a standard turbo tune, and if so what other bits do I need to go with it?
(assuming it works)
Apologies for the n00b post, but your expertise could save me a heap of research time!
