Not sure wat bc u have, but if there is a more reliable one available, i would invest in it... drop another renesis in there and go again. Dont give up. A boost controller can break on a 20b setup or any engine. Just a freak mishap

Well this what i think makes a good builder. U dont know unless you try , fail make the proper adjustments for improvement and then try again.
Umm possible upper intake manifold in the works.. maybe??

Why? The manifold didn't break.
The exact same thing. Maybe more damage to the housing, not that it would have mattered.
Actually, the MAF might have covered t to some extent. There wouldn't have been enough fuel way before the MAF went out of range. We were already at the end of the injection system when we still had 100 g/sec left on the MAF on the previous dyno session.

So...Elliot made me a deal i couldnt refuse....ill put the 20B on hold for awhile...gives me time to learn how to weld anyhow 
As E and Nick kno...we're going big.
Thanks for the support fellas.
ps:
f*ck boost controllers.

how about one of these :
Turbo Fuse
Product Information
Ok, so the GFB Turbo Fuse is not technically a boost controller, even though it's in the boost controller section. It does however have a very important place as part of a boost control system, so read on!
“Bang for your buck” is not always a good thing...
When driving your turbo car, the last thing you want to hear is a BANG! Unfortunately, the very nature of modifying cars to make them go faster means the chance of blowing the engine increases. Alter the boost-control system or use cheap components and the chances are even higher.
The new GFB Turbo Fuse is an important safety measure against such a disaster. As its name suggests, it offers reliable and effective protection for your turbocharged engine against over-boosting. Simple to install, it can be fitted to any turbo car with an existing blow-off or bypass valve in less than a minute.
How Does It Work?
The Turbo Fuse works with the blow-off/bypass valve to relieve excessive boost pressure when triggered. It does this by shutting off manifold pressure to the top of the blow-off/bypass valve, which will subsequently blow open and relieve the boost pressure.
The Turbo Fuse operates in only two states - either on or off. Unlike ineffective pop-off valves of a bygone era, which simply comprised of a spring-loaded valve, the Turbo Fuse does NOT slowly creep open as boost exceeds the trip-point. The response is instant and complete.
Who should use a Turbo Fuse?
A Turbo Fuse can help protect ANY turbo engine. Over-boosting can occur as a result of a sticking wastegate, popped or split wastegate hose, a faulty boost controller, or even an accidental incorrect boost adjustment. Of course, an over-boost will invariably occur during the times when you shouldn’t be watching a boost gauge. Even worse, a large over-boost can destroy an engine in less time than it takes to read this sentence.
My car has a factory boost cut anyway - why do I need a Turbo Fuse?
Most turbo cars feature an electronic fuel cut that performs a task similar to the Turbo Fuse. However, in the world of modified turbo cars, it is common practice to bypass or disable this feature (through the use of a “fuel-cut defender” or similar product) in order to intentionally increase boost for better performance. In this case, the engine is left unprotected.
In addition, anyone who has unexpectedly hit the factory fuel cut will know that it can catch you by surprise. The engine loses all power, which can be merely annoying or downright dangerous (when overtaking for example). The Turbo Fuse is not as aggressive in cutting the engine power; it is more like hitting a “soft” limiter, which is much safer if it is unexpectedly triggered

How would the "turbo fuse" be adjusted to now blow off to early or at a lower PSI then you wanted. It sais spring operated, would it be different springs like a wastegate?

Sure it is.
No physical engineering needed and no new parts in the air path. No new valve design, strange intake path work, etc.
You take the pre-existing BOV, the pre-existing vacuum reservoir (brake power servo), a pre-existing solenoid (VFAD) and just hook it all together with a $10 Hobbs switch.

it seems to me it would make more sense to have a safety control scheme where the ignition supply voltage is disengaged whenever the boost exceeds a set limit, would be fairly easy to setup and you could have it so that the ignition key has to be turned off and engine restarted to reset it.

Looks like i will be purchasing a GT35 hybrid from Turblown for my build in the next day or two. Basically it will be used in place of the esmeril turbo. I just need to put the turbo on and get the car back together along with installing the meth injection, and i am ready for the trip to TX for a tune. Curious to see what this style of turbo will do on my car without the Turblown manifold. I am also going to go with the smaller A/R then what was used in this thread.
