just installled the o2 clamp. followed all instructions and read all the feedback on the installation on this forum. took it out for a test drive and now the car does not reach full boost. im thinkin it may have somethin to do with the pressure switch and where to tap the vacuum line. does this make sense or am i completely off? anyone in the san diego area with this setup?

 

Which Vaccum did you tap into, so others can know.

 

problem solved, just tapped to the wrong line, thanks

 

Repeat slidin miata's response. Please post (hopefully a pic) where you tapped into that was wrong and the proper solution! Everyone can benefit by your problem and correction.
