In the 3 weeks from my purchase to getting my efi live, he never replied for a week. Assuming he was gone somewhere. But he had probably sold out of the autocal and because of covid, had to wait longer than normal for replacements. I also never sent him a bunch of emails that week. Just 2 I think.Please keep us posted i was just about to hit the purchase button. He was quick to get back to me on the question i had. Maybe he's taking some time off.
