Hey guys, running a boosted LS7 with an A4 and I've heard mixed thoughts on whether or not you should lockup the converter in 3rd gear at WOT. I'm running a Vigilante 3800 multi-disc converter in an RPM stage 6 A4. Any reason to not have it lockup at WOT on the street? I know it gives you higher dyno numbers to lock it but do you really gain much on the street? Thanks.

How much of a MPH or ET gain you end up seeing from locking the converter is a general indication of how efficient the converter is.

With my Yank SS4000 as an example, I've made back to back runs with it to compare unlocked vs. locked and saw a 1MPH gain but almost no ET reduction. Other converters (like your Vigilante) do show noticeable gains due to the fact they're not as efficient as they could be while unlocked.

I may have to take my laptop and try it both ways at the track to see if I notice any differences in ET or MPH. I just don't want to burn up the converter. Thanks.
