Hey Guys,

I'm looking at buying an '04 3l patrol which already has a heap of mods (not too sure about this one yet) and id be interested in doing this and fitting a catch can, is a dawes valve needed/recommended with this mod? It already has boost and egt gauges, chip, 3" exhaust etc. Just worried about overboosting and the like. I dont know all that much about engines, although I have learnt heaps over the last few days just from reading through forums so im not complteley incompetent haha.

Any help would be wicked,

Cheers
Gunner
