BEWARE!!
I shipped a Denali cluster to Coastal Flash for my 2018 Silverado 2500HD diesel. Living in Canada, it just seemed like the easiest solution. It was an absolute nightmare. After shipping it to them twice and it still not being right I asked for a refund. This was a 6-month process. I heard every excuse in the book. I then got in contact with WAMS. It sure sounds like I’m not the first person to go through this. WAMS was very professional and told me to ship them my cluster so they could have a look. Once they received the cluster they fixed it and had it shipped back to me within a few days.
Save yourself a huge headache and go straight to WAMS.
