@ Prandelia - so what exactly did you do regarding the tune? How did you tune your diff?

I currently have my diff out and yesterday I went ahead and opened the OSG unit. My plan was to release some of the negative preload springs which would result in quicker lockup.
Stock I have 4 sets of 3 springs, each 28kg - one on either side. That totals 336kg of negative preload. I removed 1 from each side and I also exchanged 1 for a softer one, giving me just 184kg of negative preload. I'm now questioning whether I overdid it? I still didn't mount the differential back, so I'd like someone more experienced to chime in and give me their thoughts.
I am thinking about keeping stock springs, but just removing one per quarter, which would result in 224kg of negative preload, which might be ideal - but I'm not sure. I don't want it to behave exactly like a welded diff...but I do want quicker lockup.

Thoughts? Thanks!

I'll have to look it up. I just let the wizards at OSG tune it for me. I let them know I didn't necessarily want it to lock up much faster, but harder. It's progressive which is nice, didn't want to lose that, just need more overall lockup, but I'm sure it does so a little faster.
