I had planned on buying one of those to eliminate the skreem problem forever but I have seen post after post on the forum here where people are claiming the skreem is just moved inside the ecu and the problem can still come back. I have a hard time believing that but until I verify how its done I havent ordered one.

Since you dont send your keys to them I would think the skreem is actually fully eliminated like they claim. But since you do send your skreem in there might be something to it so not so sure. If I know the no start skreem can never come back it would be money well spent to me.
