Finally got around to fitting my new electronic boost gauge, Theres a small boost sensor supplied in the kit, I need to tap into a vacuam line in the same place you would with a normal boost guage. The instructions are very vauge as to where the best place to do this is?

 

Ok let me make this easier, should I put the tee piece in the dump valve line or the brake servo line?

 

anywere that runs into inlet manifold really mate.

 

Have you removed the airbox for a cone filter?!

If so use the outlet that the pipe off the inlet went to the airbox. Or if need be T off that one. Would avoid doing it off the mapsensor one!!!

 

Ok I tee'd into the brake servo line right beside the inlet plenum and before the check valve in the line. At idle the boost gauge shows -20psi, when I rev the engine however it won't go into positive figures just goes as far as 0 as I lift off and the dump valve activates. What am I doing wrong?
