4l80 relay unlock issue

I've done the relay method as per slow67 and as I'm cruising around 70-80mph It will occasionally unlock and then lock back up,maybe like a 2-3 second delay anyone had this issue? I'm sure its something in the tuning...

I'm pretty sure Geoff has adjusted the tables but don't quote me on that.. Just wanting to get some ideas to throw at him next time I go back...
