I haven't dealt with Sonic Tuning much, but I did meet Ray last week when I decided to drive up to see the warehouse. Overall nice guy and said he would always provide the hookup.
At that time, I bought a pair of HID bulbs, which he said have a one year warranty and if anything happened, just to bring the receipt to him and he would take care of it. That to me is great (my buddy bought crappy HIDs and they keep burning out but the refund/turnaround time is awful). Knowing that I can take it to him for a replacement is great.
My friend bought the MTEC AE on site as well and we will be putting those in shortly. Hopefully an LED won't be burnt out!
Question: I know you are probably mad with Sonic Tuning, and I would be too, but why not go through MTEC directly? They might have been able to help you out better.
