Best Performance Upgrades?
Your engine has one head, and you don't really need to upgrade your BOV until you're running elevated boost levels on an aftermarket turbo 
Search around a bit, the basics of Evo X modding have been covered quite extensively, and a few companies even offer pre-packaged staged kits.

yeah 350-360 on e85. not on 91/93.
As for your mods, you deff want, exhaust, hfc or tp, uicp, intake, fmic, if you're going with e85 than injectors & fuel pump, and of course a good tuner.

<-------352WHP on 93 without a single problem. On E85 with FULL boltons you ought to make 375ish on a dynojet
Keep your TQ around 350 and you are good to go.
I was going to dismiss getting an intercooler for now. However, after extensive meandering research I've made the conclusion that it is worth it. Reviewing dyno sheets from members shows consistent increased results and stable cooler air temperatures. I believe that helps reduce knocking. Especially if only using 91.
I'm also at 350 range with my tune. and I don't have the FMIC or injectors put in yet!

ummm my friends are making 348-360 whp with just bolt ons and 91 octane...and one of them is on e85 and hes making 420ish I believe..and this is on street tune
A Intake and a Manual Boost Controller are the two best first mods for the Evo X. AMS and ETS both roughly claim an additional 50whp with their Intakes + a MBC with a tune to dial it in. Both AMS and ETS also have package deals for the Evo X that will get you in the ball park of 400whp with proper tuning.
I have a test pipe, cat back, intake, upper intercooler pipe, 3 port, fuel pump, and injectors. I make 355 on 91 and 380 on E85, both on a Mustang dyno. A tune on a bone stock car can easily net something like 50hp.
