That's basically it, I called them and they asked about my trucks specifications and asked me what my goals were and they flashed a computer and sent it to me, then I installed it and sent mine back as a core. Pretty simple, this company is in Canada but they were very helpful, explaining how to ship the core back, and I think they will send you a free reflashed computer in the future if you make any upgrades, all you pay is shipping and the core charge until they receive your core. My experience was very positive, it paid for itself in no time at all.
