I run a Greddy Profec-B SpecII electronic BC. I like it a LOT. It has a bunch of features to keep you from boost creeping/spiking and has warning levels and cutoffs so if you spike the controller will know it and drop your boost level. It's very very nice. :goodjob:
The BC will feed into your vacuum lines and change when your actuator style wastegate opens up to vent the excess pressure. It's an easy job.

Sounds like you've got a premade toy there. Not a fan of the front bumper, but hey... at least the motor's done well.

I'd be careful leaning out especially with boost. You require a lot more fuel when you have a turbo than you would otherwise. Do you know what cc injectors you have? The blue box is part of the Greddy kit. It handles some of the fuel/ignition management, but is pretty narrow and unflexable. It's a good thing that you have a VAFC in the mix. That will give you some tuning capabilities.

Quite honestly, if you're referring to an Air/Fuel gauge, you're not getting accurate readings and you shouldn't trust the thing. They have been found to be pretty inaccurate and are more for a "general idea" of where your air/fuel is. Be careful relying on that thing...

I think you can safely push 8 psi, but I wouldn't push it. I have lowered compression and stock sleeves and I don't plan on going past 14psi until I upgrade my sleeves. If you want to keep your car running well, don't push its limits. If you do want to go balls out, do some internal work and make it strong enough to handle the extra power.

Glad you started posting out here. Nice to meet you annnnnd!
