Default STS issue or boost issue

Since all bs is out of my system I started reading some of what is going on....my EBC is basically hooked up wrong and so right I am not leaving it alone at 5 psi...something I can fix in the future...but next issue

My car shuts down every couple of seconds. For example at the stop light I lose some battery power, car exhaust stops then picks back up, and engine feels like it is going to die...I dont know how to solve that issue..

Next issue I am having at 10 psi and 5 psi I am having the same issue. Issue is when I press on the gas to go when I hit max boost my car like stalls, bogs down and I dont go anywhere while the gas is floored so I let off it. I am not sure about this issue either. It stalls at 4 thousand rpms or max boost and then at 5 psi I can 1 mph a minute. I dont know if the EBC has something to do with or not but would be good to know.

I have the log file and when it goes from 0 to 5 psi starts at 5.5 kr then goes down to 2.0 kr...I know that is not good......so I was wondering would the EBC cause this and just running off the wastegate. I only can go up to 4 thousand rpms underboost then the car basically bogs down...

Sounds like a tuning issue.

Well I believe it might be but I am still trying to figure that of tuning but it is weird though that a tuning issue may cause me from going past 5psi and 4 thousand rpms and stall down

doesn't sound like an STS issue at all as your knock readings are horrible.... who tuned your car?
