The power comander -3 has worked out great for me. I simply took it put of the package,installed it on my 2007 dresser, then fired it up .No adjustments needed.You can't ask for anything more than that!

The product was easliy installed, easy to use, and works perfectly. I would reccommend this to anyone who does not want to pay double the price to a Harley dealer for re-mapping the EFI.

Easy install. I had to use the online dyno software. No biggie. I also called their tech support and they were very helpful. Had the retrofit set up in about 2hrs. Easy DIY install.
