dvs-b4

thats where i took it from the 1 line at the botem is for the bov and waste gate the 1 in the midle idk where it goes to nd i jst chose the top 1 lol nd it works for me

i used to have mine off the same place bt have moved it couse it wasnt reading right is urs reading about -12 to-14?

i think -20 aplies to all cars nd if it does sit on or around -20 u myte have a leak or a bad vacuum line to T of speaking from experance

shit mine neva sits over -22 bt does get up to -12 when cold bt corrects its self

u have a b4 right? where have you got the T intersection for the boost gauge? yea -9 to-7 sounds about right thats what mine does if i put my foot to the floor i hit 16psi of boost prity quickly but by then im well over the speed limit

iv taken my boost gauge off that line nd put on another nd reads fine nw it sits at -18 to -22 but creaps up to -12 when its jst started and its cold bt cmes right within a min nd boosts to 16psi i was suprised

it sat at -20 when i had it plumed to were the wast gate t was (instead of the wastegate) bt have extended the pipe and teed it off from there nd corection lol its -15 i cnt read lol it boosts fine nd is stedy at idle

hi all just wounder what the normal vacuum should be for a b4 leagcy twin turbo? mines siting at -13 and was woundering if thats normal and ok thanks in advance

i put a new peace of pipe in and teed it off there it reads of 15 vacuum is that ok? it read 20 when the waste gate was unplumed! 1 more thing is it ment to drop back to 0psi when the second turbo kicks in?

it does both boost and vacuum. it worked ok and read both boost and vacuum off where the wastegate was bt didnt hold at max even with my foot still on the gas it peaked nd droped back to 0 so idk it may have been leaking. there are only 3 pipes comeing off the throttle 1 goes towords thr fire wall 1 turns and comes toward the front and the other is the bov

hope this works

yea its twin turbo its only got 1 bov that i know of its straight of the top mount intercooler ill try upload a pick bt its proven harder than i thaught

sweet thanks for that ill let you know how it goes

will it interfear with anything? would it be allright to extend the line so i have enough room for the t

hi all im new here and was woundering if any 1 could help me? its a 2003 legacy b4 my problem is iv got a boost gauge and am not shore where to put the t intersection for the vacuum line. iv thaught of puting it on the bov line but theres all ready a t there for the waste gate. iv tryed unpluging the waste gate signal hose nd runing the boost gauge of it but it idels real rough when its not on. the pipe isnt realy long enough for a nother t and was woundering if any 1 new another place to run it from. thanks in advance andrew
