Hey im ordering a PCM from 3800performance. I have a couple questions as to how i should go about this. They have a refundable core charge of 100.00 if your original core is returned within 14 days. Or i can send mine in to be reprogrammed. I just am sketched out about sending it in and having it come back half programmed/****ed up. Has anyone sent them their core PCM and get it back nicely reprogrammed? If so let me know and i will send it in asap. Thanks
