I did my homework and found TTS to be better at the time I bought it. I also didn't ask questions on an OPEN forum and then complain about the answers. Nuff said. I'm outta this thread.

The reason for the original visit was to "tune" the WFO (100% throttle) conditions because it is almost impossible (unsafe / illegal etc) to do it on the road.
My gain from the dyno (using the TCFI-III) was nominal. As I recall, it was less than 10 HP & ft/lbs. I had already spent a very long time working on the tune with the DTT. While that may sound like a lot, it's really not on a big motor and because it was only 100% WFO it did not impact "rideability" at all.
I "think" that's what you were asking...
Now,with regard to the DTT vs SERT.... on paper (dyno sheet) they look all but identical. HOWEVER, what I now call rideability, was totally different. With the properly tuned SERT (same as TTS / SEST / DL), the throttle response everywhere is as smooth as glass and sharp & crisp ~ all at the same time. I have never experienced anything like it on a Harley before that tune. The rideability results have been the same on every bike I have taken back for SERT, TTS, SEST, or DirectLink tunes. The numbers vary, based on the degree of motor build, but that "crisp", "snappy" rideability is always there.
It may not be something that matters to everyone, but sure does to me ~ know that I know it's possible.

since a dyno tune costs $$$ that a TTS or SERT/SEST needs... I'm happy with my canned map on my PC V that Fuel Moto set me up with.. prob with countless hours on their dyno machine, no dB pop and about 14 more hp/tq without cams or anyhing else besides mufflers and ac intake.

I think I am going with a TTS. I had/am having very very bad luck with the PCIII and am not recieving a terrible amount of help from dynojet. For that reason I am now very hesitant to a) buy another dynojet product and b) use another piggy-back system that goes in a bad spot and is exposed to bad elements of weather. I have dealt with Steve Cole at TTS when dealing with diesel tuners. Im not sure if he deals with the Mastertune too, but imagine it must be him that does. He is incredibly skilled and knowledgable and is top-notch when it comes to customer service, tech support etc.
I am a little nervous however. I know nothing about tuning a motorcycle. I am wondering, if get the TTS, is there someone that I can contact who can send me a MAP for my bike or one with a similar set up? Then I could speak with this person and tune the bike further if necessary in order to eliminate a decel pop, flat spot, or what have you. Can anyone reccomend a knowledgable tuner in the southern NY, Western CT area?
thanks

At least call and talk to Jamie before making the decision, as he sells both the PCV and TTS at excellent prices.

I hate to rub this to a nub, especially if you've decided to go with TTS, but you should reconsider the PCV from Fuel Moto. They will give you excellent customer service if needed, a double-waranty (2-years), and lifetime maps for any hardware changes you will make. Their maps are excellent and you won't need a dyno tune, all for $300.
