The lockup you are talking about is your torque converter lockup and what speed it locks at. This is basically which speed your truck goes in overdrive it feels like it goes into sixth gear (I believe). I have mine set at 50 right now and I like it, before the tuner my truck seemed to lock at around 40 and it drove me nuts because the truck seemed doggy until higher speeds. Around my area the speed limit is 40-45 on many roads and the truck just seemed like it was shifting to soon but no now. With the lock up at 50 it seems like the truck runs stronger and isn't as sluggish when the torque converter locks. just my opinion.

No problem. Actually you download the torque converter speed lockup file from the H&S performance website and then save it on the storage disk that goes in your Black maxx or mini maxx. I believe they come preloaded with the 55mph file from the factory.

I've set mine at 45 mph. Set at 55 it was running at 2100rpm in town because I wasn't going fast enough to lock up. I'm hoping set at 45 mph (around 1300rpm after lock up) it will help my mileage.
