boost creeping issue..

veep ---> nope....boost controller measure boost from the turbo to intercooler piping while the boost meter measure boost from the plenum

You realise that the pressure that will be between the turbo and the intercooler will be different to the boost pressure you are running.

The feed to the boost controller, MUST be taken from a good feed after the throttle plate.


the pressure between the Turbo and Intercooler may be remaining constant, but due to the flow of the cooler and the temperature of the day the outlet pressure of the intercooler may vary by quite a bit.

yeah i know when i say vacume line i dont mean 2.5inch boost line i mean 5mm little black vacume line

sorry, changed the quote in my post,

Renxun - When you say "boost controller measure boost from the turbo to intercooler piping" do you mean turbo as in wastegate in exhasut housing and intercooler piping as in compressor housing?? cause thats how it should be, and made as short as possibe to eliminate boost spikes.

er... im not sure what u mean .... maybe i can xplain it like this... i take the boost signal for my boost controller from :

turbo compressor outlet will be the piping that plumb to the intercooler....at the same particular piping i make a nipple there and get the boost from there to my EVC

The boost controler should be sitting inbetween the wastegate and compressor, like in the picture. Its made to bleed the air going to the wastegate so the wastegate doesnt get the full pressure load to open the stock spring
