I have an '03 and went with the SE high flow air filter and a power commander with rinehart true dual exhaust. Dyno results were 106HP with 111.4 lbs of torque. I had a Power commander tuning center tune it.

It is loud and has enough low end torque to lift the wheel off the ground with a twist.

Big Sal,

My first post ever goes to you because your "lift the wheel off the ground" post has inspired me to start buying Pipes, PMIII, & Air cleaner for my yellow (don't laugh at my company colours) 2005 which arrives in February. Your bike sounds great & I liked your dyno print out. I had preferred Thunderheaders till I read your posts.

Regards
Tony

Just a reminder. HD now has a Race tuner that some people say is better then the Power commander. I Still have the PC installed and it limits the revs. You could get more revs with the race tuner but for me I would probably blow the thing up, So I left it alone. The rineharts really are great performers and also the best looking pipe around.

I may be wrong but I am planning;

HD Flash upgrade (to increase rev limit to 6200 RPM)
Power Comander III (so that I get bespoke tuning on a dyno rather than guesswork)
Thunderheader 2:1 or Rinehart True Duals (Big Sal is swaying me)
SE Air Filter Package

The UK importer & distributor for Dyno & their rolling roads is 15 miles away and although they only advertise for business from pocket rockets I figure that they will know more about using a re-mapping programme than some HD dealer who has no rolling road and is selecting a predetermined map from an innadequate (for 103") HD option list.

I bet that Alaska is better equipped to mess with HD motors!

There is no Alaskans on here is there?

I personally like the dual pipe look better then the 2 into 1. I have 2 bro's with 2 into 1 exhausts and I am not impressed by the performance on the 103 stroker. Rinehart makes pipes for numerous NASCAR teams. There must be a reason for that. Much money is up for grabs so you would think they would run the best pipe. If you  go with the 2:1 please post the dyo results.

Here are some runs on my flhrsei2, se air filter, dealer flash, Rinehart True Duals and the quiet baffles.

Where were the runs done. In a shop or in one of those portable truck mounted Dyno's. I am just curious. I would think the HP and Torque would be better. I heard it said that a 103" motor should put out around 100 HP. I notice that the peak HP on your runs are at about 130MPH and on my chart they are at around 110 MPH. I wonder if there is a vast difference in dyno machinery. I would assume all Power commander tuning centers have a PC dyno, But I am just assuming. I really don't know.

[fxdjerry]

The runs were done on a portable dyno by DR Dyno. I think the results would be better if I used the larger baffles but I am using the smaller quiet baffles. I dont't have a clue as to what revision the flash is at. There is no PC or DFO on the bike. I switched to the smaller baffles for less sound but they are still loud. I do have a lot less decel events now then before. I bought the bike used with 1200 mi about a month or two ago. I have about 3500 mi on it now.

Ok, I guess that the difference is the power commander, And professional tuning by Rosa provided the increase in TQ and HP. Thanks for posting your results.

BigSal, I will look at the pc or race tuner down the road. I am on info gathering mode very new to Harley FI and appreciate your posts. Thanks

Good luck and please let us know if and when you make any changes. And if they improved the performance.

THanks for the info, if I decide to go with aftermarket exhaust (Rheinhart Trueduals) and SE aircleaner, can these be installed before I break-in the engine?

if you set your ignition in the 100% throttle position on the power commander to 5.
you will get your revs up to 6500 rpm's.
what you are actually doing is advancing your timing.

Does that mean that I don't need a HD flash upgrade in order to up the rev limiter?

Tony,
The information that I have is, that when utilising the PC, the reflash of the ECM is only accomplished by the re-flash of the upgrade chip.

[kng103]

tony,
if you have the power commander, then technically you dont need the reflash.
however, it is a good idea to do the reflash just in case your pc ever craps out.
the you dont have to worry about the bike running too lean.
