I've had OZ Omega X on my '21 for about 2 months now. Huge improvement over stock.

I'm curious what you did with the idle speed. I reached out to them this morning about lowering it back to stock and they are recommending that I go to 5w50 oil if I do that.I just installed the OZ tune about 2 weeks ago. I had trouble withe the trans shifting crazy while using cruise when i would hit an incline. They also raised idle but i liked stock better. I sent them an email and they fixed my problems right away and the tune is great now. I had no problems with the X4. I like the fact that i can put any fuel and not have to change tune. Plus getting rid of CD was also a plus.
