My brother added an air cleaner and Thunderheader slip ons and got the Stage I download. It runs okay, but he pings and pops from time to time. OTH, I have MO slip-ons and the SE Heavy Breather and I used the Fuel Pak and it works well, though I feel the engine runs a little hot. Hope this helps...

 

I added a K & N filter & a PC-III. Later I added a Supertrapp 2-1 exhaust. I changed the map to work with the exhaust. On a trip to Arizona the bike started running badly. The dealer I took it to told me it was probably the PC-III, & that I needed to buy a SERT. I passed, but the performance got so bad that I eventually disconnected the PC-III. I ran the bike about 3000 miles without the PC-III. Eventually I found out that the ECM was defective & Harley replaced it under warranty. I've since re-installed the PC-III & the bike is running just fine.

Bottom line, just a K&N filter & exhaust change & you *can* run without any changes to gas/air. A Power Commander is a much less expensive way to make changes & will adapt to any mods you make.

*EVERY* dealer that's found out that I have a Power Commander has some ridiculous story about why it's bad for the bike & why I "need" SERT. It's some of the most pathetic sales crap I've ever heard.............

 

Fuel Moto all the way. PCV

 

Stage one down load only, No issues, Save your money.

 

Thanks for all the great input, guys. The service manager I spoke with said HD is seeing alot of problems associated with the PC units, so I think I'll go with my plan and use the V&H Fuel Pack.

 

its funny how the dealers will see a pc and without even a check they know its the pc ?take off the pc go to a different dealer and wouldnt ya know it they found a bad sensor.put pc back on and life is good.

 

I added the SE pipes, Arlen Ness Big sucker, and the download on my '08 Ultra and it runs great, cooler, & quieter. I do not thing you need a sert or PC 5 if you do not go to the 103 pistons & cylinders with a cams change. I did all that on my '07 Ultra, and it ran great with the PC 3. I finished with 84 hp & 102 tq. My '08 Ultra without the 103 kit has 72 hp & 83 tq. I got 35 mpg on the '07 & I get 55 mpg on the '08. I recon now the choice is yours

 

Only reason most Stealers give Power Commanders a Bad rep is they don't know how to tune them plus can take your PC off and reuse it on another Bike ... Will stick to what I said ..

 

The Fuelpak was an easy install, simple to setup for my 08 Ultra and works great for me.
