Its not really the brand. You get to a certain level of looseness and then you notice it.

 

I have a Yank SS3800. I haven't had any problems with it. I used the Predator to delete the Torque Managment. I think that's the only way to beat it. I haven't run my car with out the tune, so I have no idea what it feels like.

 

hey wassup.3000yank here.no problems at all.

 

Yank Thruster Pro 4200... no probs here.

 

I just installed my Predator today. I must admit ,it did help my car out alot. I still have that "stumble" ,but it's not as bad. I set it up to shift quicker and firmer. So now, my car shifts from 1-2 around 2400rpms . Thats just before the stumble would come in at. So far, my car does feel much more responsive than before and the driviability is much better than before. I can live with that little "stumble" now cause it's nowhere as bad as it was before.
