i install my boost gauge & i wonder if i did it right =)


at idle stay 17-19 ishhh vac normal?

i route it by the driver side pillar

cut the vac by intake manifold & install T Fitting.
the first problem is when i went to RRE they attach their gauge to the fuel pressure regulator --->>>
and they manage to set the boost about 19lbs & it holds
but the one i did it only shows 15lbs.
what can be the problem?

sorry about my grammar/english =)
thanks for advices/help in advance

 

i was searching to see where people get their vac from for boost gauges and its either the fpr or the bov/manifold where u got urs. not sure why low boost, possibly check for leaks?

 

there is a vac line right b4 TB that's where i attach mine. i was thinking because i got zip tie not clamp on the T fitting prob there's a leak i will go check it.
