Vig 3600 won't lock up on Dyno!

Had my car tuned yesterday and the tuner was unable to get the converter to lockup.. I've heard that you have to use a Tech II or a manual lock up switch. Is this true or should he be able to lock it up with LS1 edit? The tuner thought that there might be somthing wrong with the lockup selinoid or even the converter. He allso said that on the unlocked dyno numbers the converter was sliping about 3-4 hundred rpm. the car dynoed 367 rwhp and 353 rwtq.

Last time I had my car dynoed (after adding the new tranny) they couldn't lock it up with edit. Never found out exactly why, here is the response:

and this one the tuner kinda replied

https://ls1tech.com/forums/dynamometer-results-comparisons/238573-added-ls6-intake-stage-3-trans-car-dynoed-much-lower.html

I'm still looking for an answer.

From what I understand the converter is ok as long as it locks up normally while driving. Mine locks up right at 37mph when I'm cruising and locks up just fine and stays that way on the highway. I still am a little concerned but why would an experienced tuner not be able to lock it up is beyond me.
