Hey guys,

I had a quick question in regards to my vacuum idle on my boosted GSR. Before, I've noticed my average vacuum would reside around 22hg constantly. It looks like it dropped a couple points and now it currently sits at exactly 19hg. I've checked all vacuum lines and now im currently pending a replacement on my bov (had cheap RFL BOV knock off--replacing with a new greddy type s).

I'm very **** about the condition of my motor so i wanted to ask around.."what is the average vacuum levels for you on boost" and what could cause the vacuum level to drop (besides vac. lines and leaks from BOV). Any input would be appreciated. Thanks

 

im at 18-19 inhg with a built motor

 

depends on your elevation which plays a big part. up in colorado we usually get around 17. lower to sea level you go the higher your vacuum will go up 20+

 

Thanks for the info guys. I learn something new everyday. Appreciate it
