I think their current price is $499. I took advantage of a special they had back in October of $475. Though the Crossfire is not listed on their website, it uses the same tuning as the SLK320. Here's contact info: http://www.speedinnovation.com/contact.php

It was simple to remove the module. I followed the procedure that's been posted. https://www.crossfireforum.org/forum...1&highlight=si

They were quick on the turnaround time getting it back in the mail on the following day. They will match whatever shipping method you use on the return mailing back to the cutomer and cover that portion of the postage in the item cost. Depending on how close you are to CA this can be done in as little as 2-3 days. In my case it was actually closer to 10 days before I was able to get it back in the car due to travel plans and I was concerned leaving the car disconnected from the battery for that long, but it presented no problems doing so.
