Yup. Perfectly good and cheap stage-1 solution. Oh, it won't be great, especially at high speed/revs, but it will be better than stock and you won't do any harm.

Having said that, Short Shots are a bit crap. They are strictly for noise and looks, they are not a performance upgrade. Anyone who tells you they are is just experiencing the effect of the noise level going up quicker as they accelerate and thinking that means the performance has increased.

 

You really don't need a download or a tuner if all you do is slip ons and a new breather! See below from Nightriders web site:
Do I need to remap my ECM when installing exhaust and air cleaner upgrades to my 07 and later Harley?
NO, you do not have to do anything. You can put the mufflers/air cleaner upgrades and ride the bike without having to worry about the engine

The simple truth is the 07 and later HD's will run just fine with exhaust/air cleaner upgrades and you do not have to do anything to the ECM at all. Closed loop EFI operation uses feedback from the O2 sensor to maintain a constant AFR, even if changes are made to the exhaust and air cleaner.

The amount of information about what has to be done '07 and later Harley when installing exhaust/air cleaner upgrades has been the subject of FUD (Fear, Uncertainty and Doubt). Riders, Dealerships, Parts Suppliers and Aftermarket Shops have presented old-wives tales, bad technical information, mis-information and in some cases, just plain flat lied about the capabilities of the Delphi closed loop ECMs on these bikes.

Most people hold on to their old ideas about what was required for the early EFI ECM's. Shops and Dealerships never bothered to learn new the new technology. Marketing information did nothing to dispel the differences between the old and new bikes. Sales staff did not know the difference or mis-represented what was required on the new bikes.

There is more independent proof that you do not need to remap the HD EFI when installing mufflers. The March 2009 (page 66) CycleWorld dyno tested a set of slip-on mufflers on an '09 FLH, getting 5% more HP and 9% more torque on a "bone-stock, including EFI mapping" bike. Cycle World is not known as a big Harley cheerleader, so it would be a reasonable assumption that they are not going to do any special favors for MOCO.

The CW information is right in line with what HD published in the Fall 2006 Enthusiast Magazine showing a 3% HP and 7% torque increase with slightly more restrictive mufflers and air cleaner kit. American Iron Magazine has also published similar articles about "no remap" upgrades involving exhaust/air cleaner changes.

How much information has to be presented to Harley Riders that remapping of the ECM is not required for exhaust/air cleaner upgrades for closed loop bikes? When it can be shown that much of the "gain" in power for bikes remapped with expensive tuning software and piggyback controllers would have occurred without spending $400-$1000, riders need to start thinking about what they are really trying to accomplish on their bikes rather than blindly following the "you must remap just to add exhaust/ac" advice that has been discredited.

American Iron Magazine routinely presents exhaust/air cleaner upgrades on 2007>later bikes without doing any ECM remap's. As one of the premier H-D magazines, you must assume their technical staff has some knowledge about how the Delphi closed loop ECM works. So you can be fairly sure that when AIM publishes a dyno sheet with improved power and the bike did not have an ECM remap, that the information is accurate.

 

i just don`t know about that, i se heavy breather, thunderheader and sert pro and can go into sixth at 60 and its still pullin, not as hard as fifth but it definitely does`nt fall on its face

 

Just realize that the ECM can only make a 5% adjustment. That's it. A stage one increases the air by 10-12% I believe

 

Prior to my breather I had already installed cobra slip ons. They had a 2" baffle in them and I didn't like it so I installed the 1.75" baffle and seen better performance. I've had the pipes on my bike now for three months and baffles for about 2 months.

Whether I need a tuner is not the question. I have it done and now want to be sure I am getting the performance that I should be getting and no harm being done to my bike.

No I am not mixing up MPH and KPH because I am in Canada and all ours are KPH. I shifted my bike at 170 KPH into 6th gear and as said above "it fell on its face". That is my concern. I had more throttle but the bike wouldn't take it. I should be able to use sixth gear or should I??

So will my computer still need time to adjust to the change?? Or is what I have, all I am going to have??

 

Simple......it's the tune period. You are never going to get any great acceleration in 6th gear as its for cruising. Thats why on the dyno they do the pulls in 5th gear not 6th. The best thing you can do is change the front pulley from 32 tooth to a 30 tooth. I assume you have a SESPT? I know of many dealers who don't even sell those as the TTS is far superior and that's what they push.TTS is the company that made the original SERT. Harley hacked it and came up with their own version which is now the SESPT. TTS offers an upgrade from the SERT for anyone that has one.

 

I do understand that 6th gear is a cruising gear but what I don't understand is my bike dies in 6th gear and I have to shift it back to 5th gear. I can't use 6th gear at all. Yes I do have a SESPT.

From what I understand the tuner is telling my bike's computer to run a certain way. Will it take time for my ECM to adjust to what the tuner is telling it??? If I get more miles on, will it settle in??

 

Might have been true prior to 2007/8 but since then the stock ECM and O2 sensors can cope with stage-1 hardware. Its only going to be stock AFR and so not as good as a decent fueling solution but it will work OK

TTS has a nicer interface, more canned maps and better help files. However, in my experience, it gives no better tune than a SEPST if you know what you are doing. After all, you are only adjusting the same tables in the ECU.

 

After I finished (even before, in fact) my stage-1 6th gear was quite useable. It has never bogged down like you describe.

I think they messed up your tune. You didn't say if the exhausts were changed, were they?

 

Yes I stated above that my pipes were changed. Not my whole exhaust system, just cobra slip ons with 1.75" baffles
