Just out of curiosity, I wanted to hook up the MAPtap and run my Synapse valve off true vacuum for a few days just to see what difference it would make. I grabbed these pics a few days ago when I was making the changes.
The CP-E MAPtap is actually a pretty great little adapter. Install is super simple, fitment is just about perfect, and since it uses standard 1/8NPT threads I was able to keep my push lock vacuum line fittings! My BOV vented exactly like it should have so the MAPtap was definitely doing its job. Overall, a very nice alternative to the symposer delete kits for tapping into a true vacuum source.
Make sure you install the silver screw BEFORE installing the MAP sensor otherwise it won't fit.
