Aircleaner, pipes and EFI

Hobbit

1. Stage 1 is the name given to the first part of tuning engine - ie exhaust/air cleaner and engine management - SE stage 1 is the SE upgrade to the orginal air box or heavy breather.
2. TFI is a brand name for an fuel injection module from www.dobeckperformance.com
3. with the slip ons you may get away with it as long you do not alter the airfilter but it will still be lean.
4.YES - if you do this option add a airfilter and fuel manager ie TFI to complete the stage 1 upgrade

Smitty, are you saying, I can keep my 08 FatBob pipes, go with SE a/c with K&N filter (not sure) and I'll get the sound I want out of the stock pipes??

smitty901

I do not think anyone ever gets the sound they want from stock pipes.
The AC changege will give you more of a kick than pipes will.
Adding more fuel will make the bike sound a LITTLE deeper.
If your thinking of changing pipes chances are you end up doing AC also down the road anyway.
So why not just skip the one step at a time game and do it right.
A full stgae 1
A set of slipons you like
SE AC with KN high flow filter
Now the fun part:
3 options here your call again.
HD download to bring fule back to stoc and 1000 more usless RPM's
Bike will run ok with a little more kick.
Add a fuel manager like the TFI, you can manage the way your bike runs your self simple and easy to use, you get the full advantage out of you stgae 1 Mod. You can remove it anytime you like and bike is right back full stock.
Do both HD download and fuel manager.
IMO a waste of 100 to 150 dollars for the download money better put towards the fuel manager. If you ever remove the mods the download is still there.
The reason I suggest going ahead and doing the full stage1 if you want to change pipes is this.
Your bike thanks to the EPA runs at the very boarder line of lean right from the start. Yes the book says you can change either pipes or AC without adding fuel. Scary you are counting on a system thats allready leaned out to make up the needed fuel. IMO your splitting hairs at this point and not worth taking the chance.
A little extra time to save up to do it right is well worth it.
You can use the time to study up on how to do the work your self.
To figure out what pipes you really want or don't want
And when you do the work it will be almost like getting a new bike
Last save you stock PARTS you may need them some day

Again, thanks Smitty. I posted a request to see if anyone has heard of the Fi2000.

I went with Reinhart true duals with a power commander the K&N. Shouldn't have to do anything else. More power now than I had with the Scream Eagle slip ons and the stage 1 set up on my Ultra.

Thanks for the info... I am wanting a little more sound and I know the fuel needs managing so I'll probably start digging. Any suggestions on an intake. Thought about the Vance and Hines Ovals but a friend just e-mailed me today and stated The guy who dyno'd his bike said Vance and Hines are not as good as some. He said they were hard to tune.

smitty901

You just want effective at lower cost or you want effective and cool looking
The SE with K&N high flow filter is as good as it gets and resonable cost.
The HD big sucker looks cool but cost a bit more about the same results.
As for Pipes find a set that sound the way you want forget what other say for the most part not a lot of difference in major quialty brand slippons.
The AC change gives the biggest part of the boost in a Stage 1`.
And IMO and I will get shot full of hole on this. Dyno is a big waste of money for most riders go with the TFI install it your self start out with suggested setting and if you like play with it form there.
You get the most out of your stage 1 at a fair price with quialty product.

I'm only going to comment on the Hyper Charger because most everything else has been very well covered. I tried one once, lasted about three hours. That was the trip to my dyno guy's place and about 15 mins. on the dyno. I was running a `01 Ultra with a 95" motor. The hyper charger killed bottom and mid-range torque but worked as claimed on top end where I never ran the bike. Installed SE high flow and never looked back. Hope this helps and good luck.
