A little over a year ago I had the dealer do a stage 1 to my '05 Wide Glide. V&H big shots, SE a/c, and the download. To be honest, I never really noticed that big an improvement in performance (although it sounds a lot better), and it runs fine. I'm new to this forum, and have been reading a lot about EFI tuners, particularly the PCIII. Seems the general concensus is that they make a big difference. I'm wondering if I should go ahead and get one, and if so does the fact that the dealer already downloaded make a difference?

 

your download will work fine with the pcIII........ you will probably gain a few horses by having it dyno tuned with the PCIII.
but on another note...........if it aint broke, dont fix it. take the $400-600 you would dump on a PCIII & dyno tune and buy something else for the bike.

 

I agree.i just got the harley down load on my dyna . and i'm very happy.save your money.
