That's what strange. So I had the T5 ECU in the car with the T5 boost control valve I have wide open boost when it's up, I am hitting fuel cut off with it set up that way. So I thought the T5 ECU or the T5 valve was bad . So I switched over the programmed ECU that is supposed to be programmed to a t7 valve and I'm getting the same thing happening. I have some new mosfets, so today I am going to change out the mosfets on the t7 programmed valve ECU and see if that fixes it. Even though I put those mosfets in not too long ago. Fingers crossed that that's what the problem is. I hooked up the t7 valve just like in my other two cars. If I remember correctly you don't hook up the blue wire at all because it's not hooked up on my other two cars and they run perfectly. Sorry if I'm not explaining myself very well. This is just really odd behavior for this car. When I got the car it was not doing this at all I put probably for 5,000 miles on it and it is acted just fine and then one day it started running wide open boost so I just assumed the boost control valve that's what started this whole thing so I just switched it over the t7 valve and ECU .
