I have one of these, its the iDII though but it's great. If you have it, why no use it. I had it on my 32 with stock turbo. Much better whan using a bleeder if you wasnt to up the boost a little and tweak the gain.
I have a fair few mods on my car now and i still use it. It holds boost perfectly(14psi currently), never spikes and the boost graphs are kinda cool too
