Hi All,

I am about to upgrade my stock FLSTC 2009 with a D&D FatCat 2 into 1 exhaust and Screamin Eagle Heavy Breather.

As far as tuning the and being new to EFI, not sure on what I need to do. The options I think are:

1.  Reflash with a fuelmap if I can find one.

2. Screamin Eagle race tuner.

3. Thundermax

4 PowerCommander.

any advice and help on the best option ?

You will find plenty of happy customers with all the systems you mention but for you it depends. Do you want to get the most out of the bike, or just good enough, and do you want to do it yourself. Are you cost/value conscious. Do you give a hoot about mpg, or are just looking for cheap power? Why did you send all that money for the heavy breather.. looks?

Any name brand tuner will liven up the bike, give you WOT power. But why are you not looking at the TTS kit? If you want to get the most out of the bike, its currently the most bang for the buck. Any of the tuners you mention will work good enough and and you can skimp if you want. The TTS and SESPT (not called SERT now) may be less trouble in the long run as no hardware is left on the bike. Of those two the TTS is currently a bit better tuning tool, and as good as it gets for street purposes. The PCV is probably less money with canned MAPs but can be a PITA to install and disables the adaptability you get from the O2 sensors. If the canned map is not adequate, you do need a relatively quick dyno run to dial them in. The TMax is more of an install effort and costly, where (if you want to do more that load canned maps) the TTS is using a couple hours of software and riding sweat equity to dial in the VEs and then lets the stock ECU manage the bike. The stock ECU does this very well. There really isn't anything better short of hiring a tuning pro to tune the bike, and many use/prefer the TTS tool.

Yositme,

I haven`t yet purchased the FatCat and Heavy Breather ... looking for max performance while still looking good.

Would prefer to do it myself, particularly if it saves some $.

So is the TTS simple enough for a novice to use ??? or am I better off getting a tuning pro to tune.

Also I am sold on the FatCat but open to options on other options besides the Heavy Breather ... any suggestions.

 

Thanks

Plenty of novices use the TTS tuning kit with success, and there is much help here if you get stuck. If you do a quick search for TTS you may find quite a few similar posts.

You can download the manual from the mastertune.net site, read it but don't let that discourage you as its pretty simple to use with the tool in front of you. If you have a laptop handy and are comfortable with installing and running software, then it should be easy for you. The hardest part for me was installing the software as I'm a klutz with a computer.

Its a full featured tool but if you want that last 2 HP and 2 Lbft of torque and last 1 mpg, then a competent tuning pro is needed (regardless of tuner you buy). The TTS easily gets you very close with A/F, its the timing where a good pro can help squeeze out a bit more. Although you can use TTS to adjust timing, there is no automated help for it or provided by any other tool regardless. TTS provides a nice logging tool so you can monitor and perhaps squeeze a bit yourself.

Off hand I don't know which is the best filter or if there is a big difference between them. Most riders get a free flow that looks good to them. Just saying that if you are buying one for performance, you need a tune to get the most out of it. Starting from a stock bike, IMHO a tune will provide significant street performance improvement, an A/F will help top end 4000 rpm up and a muffler sounds good.. most hurt performance a bit unless you go 2-1 style like you are doing. The A/F and pipes will give you HP/torque numbers to brag about WOT, and help you in a drag race. You live with a good tune otherwise.

If you are the type that will perhaps add a drop in cam next year and some headwork and push displacement the year after, you can retune with the TTS tool yourself as you go along, you are not depending on anyone.

TTS is way simple I am complete and utter idiot and I got my bike tuned well with it, like posted above any issues just post.
