Ecm Reflash

Hey all, I see quite a bit of the sending out the ECM to get it reflashed but does anyone know what software is actually being used? I've searched around but never came across anything solid. there is all kinds of hacked BUDS2 software floating around but I was wondering if there was a reputable place that has it. I don't mind spending money but when I spend 400+ I want to be able to change things constantly without sending my ecu out every time. Thanks and cheers

wheel question

My rear right wheel is kicked out at the bottom, what could be causing this? I am going to try and do this myself. I wasn't sure what to look for other than the wheel being cocked to one side.

Thanks
