Is it really necessary to add an aftermarket fuel controller if I only plan on doing air cleaner, and true duals. I have heard negative things about the factory stage I download, and I definately don't want to risk detonation. BTW, I have '06 FLHXi w/25º injectors, if that makes any difference.
I bought a used '03 Ultra Classic with 4300 miles on it. The original owner had a Stage 1 intake and exhaust installed and what ever the download that the dealer service department did. I replace the muffler with the original stock muffler because I didn't like it that loud. The bike is still running very good getting 50 to 51 mpg on a road trip.
I like performance but at today gas prices, I'm more concerned with mileage.
Seems to me that the download is not popular here.
I have a new 2006 FLHXI (25deg injectors) with slip-on mufflers and the SE air cleaner, with the Stage 1 download. My independent mechanic, who I've used and trusted for all the work on my last three bikes (12 years), has done literally hundreds of the downloads with no issues at all. I trust this guy, and his record speaks for itself. On the other hand, when I asked my dealer about their preferred method of fuel delivery modification, they said that all they use is the PCIII and a dyno tune for a cost of $650. Seems to me to be much more lucrative for the dealer. I inquired about a SERT, and the dealer steered me away from it.
I don't understand why folks say the download is a waste of money, if you don't plan on doing any future mods to your bike. My bike runs strong, with no hesitation, overheating, stalling, pinging, popping, backfiring, etc. I did the complete install myself (except the download, which was done by my mechanic) and save $900 over what the dealer would have charged me for slip-ons, air cleaner, PCIII and dyno.
One of the things the Stage I download does is to up the rev limiter. The newest Power Commanders can do that according to a note on their website. That means you can save the H-D flash and do it with the PCIII.
Not all bikes have an issue with the flash...but a lot do. It isn't the mechanic that sets it up...it is a computer download from HD. All bikes are built a little different and therefore some still run ok afterward.
Odds are, you will experience a problem. As many others had problems, so did I. I went with a PCIII and have never regretted it since.
