Does it look like this?

I put mine in place of the larger black hose in this pic. Basically one end goes into the boost controller (same as the one pictured above...ebay special) and the other end goes back to the lower side of the metal line.
Works fine and has been able to supply me with up to 19 psi on a regular basis... Just make sure you tune it the first time with the valve all the way open so it doesn't spike/overboost on the test run.
yeah - it looks a bit like that, but my pipe was all metal - no rubber hose.
I'll get it set up properly soon. but i ran out of time with fitting it so just rejoined the pipe with a rubber hose and left it like that for now! I'm on a 12hr night shift and all i really want to do when i get home is sleep!
I fitted mine yesterday, climbs up to 1.2 Bar

. Now all it needs is more fuel!
I'm going to buy this for my GTD.
However i'm wondering MontanaGTD if you could show me pics of your install, or just a pic of the general area, i want to understand more clearly what involved..
Also are the instructions any good?
And what about a boost gauge so i no what boost i'm running? anyone got a link on how to fit one of them or?
cheers,
Boost gauge just uses a tee to hook in, and has a hose between the gauge and tee. Probably best to put it around the intake or on the line to the LDA.
