Default Stumbling with ECUtek Part 2

i perviously posted a thread about how my car would stumble while in boost after swapping ECU's with a friend of mine. which can be found at http://forums.nasioc.com/forums/show...hreadid=333008

Now since I put the white restrictor in that Shiv tuned the car with it doesn't stumble while in boost only when I left off the throttle. When I say stumble I mean a very violent shake through out the entire car, feels like you hit the fuel cut off when you boost to much. I tried resetting the ECU several times and my check engine light will not go off. I was told by my friend that its my blow off valve, though I adjusted it a bunch of times, loosened it up tighten it up between, etc., still no luck. IM starting to think it was a mistake on swapping this. I though it could be my spark plugs but I don't no. tomorrow morning IM getting my codes pulled from the cel so IM sure it will tell me what's going on. If anyone has any idea what this could be please let me know thanks.

Here is how you can look at it. Your friend went out and bought a
taylored suit. If your not the exacty the same weight and height the suit isn't going to fit and nicely as it did on your friend.

The WRX's are really different from car to car. I have seen stock
car run from 165 whp to 192 whp bone stock. They really differ.

You'll probaly need a custome tune to get that perfect fit.
