Got a question for u SS/TC people. I have 07 SS/SC. Just put a TVS in the car. When i was on the M62 i had a 2.8 pulley. Gauge was canadian so it was in kpa...hit 130kpa (18psi) So i had to buy a new gauge, decided to get the american version of the SS/TC gauge (30psi) With the m62 still in i was hitting 25psi and now with the tvs in im hitting 27psi. So the SS/SC gauge read 18psi with the 2.8/m62 and the SS/TC read 25psi on the same set up. Someone mentioned i need a sensor from the SS/TC. Anyone know what that sensor is and where can i get it. Pretty annoying cuz i know im not hitting 27psi of boost.

 

Why not just get a mechanical boost gauge and hook it directly up to the nipple (or tee it in) on the intake manifold?
