A tester is pretty cheap (less than $50) and is pretty much mandatory for any FI application. Everything could look nice and fine but you could be blowing past the injector seals and not even know it.. and a boost controller won't fix it if you're only making a couple PSI as most wastegates have 6-8 PSI springs minimum. I never have seen the kit before so I'm not sure what parts it uses, and if they're genuine or knockoffs. I've had great experiences with TiAL gates and wouldn't use anything else. Most EWGs have a boost port and a separate vent port so make sure not to switch them up when installing it. Finally, if it's still not boosting I would check the turbo(s) for shaft play and go from there.</blockquote>
