Turbonetic kit engine stalling, anyone else beside me?

I remember now having similar problems, cheap vacumm hose supplied with the last turbo system I had all stretched out and I had several leaks. Once I replaced all the hose it was running just fine.
At 10.5:1 compressioin on my Matrix with 12 PSI of boost I had issues with misfires under load at around 4.5k RPM and higher, even with colder Iridiums, gapped properly. I tried Platinums and not much improvement. A very good tuner suggested regular NGK plugs, the cheap ones, car ran perfectly after than, just had to swap them out more often.
Toyotas independent coil pack systems are very effecient and have been used effectively on many high output turbo applications, I would stay stock in that department. Unless of course there is a proven need to modify it with dyno numbers, real world experience from a trusted source, time slips, etc.

wow, just changed that then man. Now where does the bottom port go then? Is it just left to be open or where does it go? I know the wastegate, the top port is open too. Does the Bottom port of the BOV go to the top port of the wastegate?

Those are extra ports that are not used in this setup. They do not affect the working of the BOV or wastegate whatsoever. The top port on the wastegate is used when you add a boost controller. The bottom port of the wastegate is used in other applications like supercharged cars, etc.

Left them open and switched out the port on the BOV and the car still turns off on me after hitting boost. I dont know what else to do.

k, i'll try that tonight and see what happens. Thanks for the tips. I just spent pretty much $5k on the kit and I just want it to run PERFECT with no problems. I'll let you know what happens by tomorrow.

So i'm the guy in SD that MIA is talking about. I had the same problem as you bro. After I fixed my BOV the car ran much better but it definitely was not what I had expected from 5K. The next morning however, i drove my long commute to work at normal conditions, never getting on it at all. On my way home I floored her and wow! Excellent and quick boost, no misfires, and of course no stalling. The ecu just needed to unscrew itself.

yeah, car shuts off completely so i have to restart the car. Yes the maf in in the right direction. If its a bad unichip, how would i go about getting a new one. The only thing is it never stalled when I had it first installed. Problems...
