Oh yeah... you're the one who's car isn't running right... My advice: Fix what you've got first.
Second, You're running a MAF, unless you've got it setup as a blow-through setup (not the best way to go) you're still going to have the same issues with a BOV.
Third, pick up a copy of Maximum Boost by Corky Bell.
Turbonetics T66? You're going to have worse fuel cut issues than you already are unless you've got some decent fuel upgrades first (namely high flow pump and larger injectors). They're a very nice, responsive turbo though I've had a lot of fun working on a couple MKIII's with them. Honestly, you're going to be pushing it with a 57 trim upgraded CT-26 at anything above 9 psi or so without fuel upgrades... so you might as well stop window shopping until you get the prerequisites taken care of.
