Here are some pics of the PCIII install on 2008 FXSTC

 

I have a post with some pics of mine. Just search for 2008 Fat Boy Stage 1. I put mine behind the mudflap. I have inspected it after about 200mi of riding and it looks perfect. The PCIII is a pain in the *** to install. I had to partially pull my rear fender to gain clearance to run the connectors under the seat. The fuse boxes have to be removed from the fuse bracket to gain clearance to store the fat connectors under the seat. This was my experience. Performance with canned map is good, but I will get it dyno tuned in the future.
