We did Eurocharged tunes on 3 crossfires here one morning a few months ago, No problems, all 3 went great. Really easy install using my Lenova / win 10 laptop.
One tune was on a NA coupe with the usual intake and TB mods and it goes Real well now , surprised its owner and me !
I have now ordered a TCM tune for my srt6 roadster along with a new ECM tune too. I cant wait !!!
