I appreciate the monetary concern ha!
Yeah it looks to be that most people with EWGs are usually and coincidentally on higher boost levels and that's where they can shine, and you're right that the 39's upper limit is only around 21psi, however I've also seen 39's swapped into WRX's who also happen to be using EWGs, with and without E85/meth. Also have seen numerous posts and threads about people(including yamahaSHO) who have reported that they have a benefit. So to me it stands that even the knackered lil' VF39 can see improvements with an EWG.
When doing headers, I was probably going to go with GTSpec and one of their compatible UPs because of the bolt pattern.
