I searched high and low when trying to find the right tuner for me. I wanted something that was smart, and I didn't have to adjust or load maps. Putting the bike on the dyno is something I like to do,.. just to see what my numbers are but I don't like dyno tuning. Power Commander makes the auto tune, but combine its price tag with the PC-V, and its expensive and I read some bad reviews on both which steered me away.
So with that said, I found 3 smart closed loop tuners,.. the thundermax, accel's SLM, and Terry components terminal velocity 3. The thundermax has great reviews, but was really pricey... to pricey for me. I couldn't find but just a couple of reviews about the accel Self Learning Module, and on something like this, I don't like being the guinnea pig. So that left the Terry comp part. There are a lot of reviews of their older models, but about a dozen of the new TV-3 for the 09 and up touring bikes. Most of the older reviews were on non touring bikes, and it seemed they did have a problem. However every review I read for the 09 and up was outstanding. I called and spoke with them a couple of times, questioning just how "smart" the tuner was. As in, when I add my stage 1 it will adjust,.. the answer was yes. When I add headpipes,.. again the answer was no problem. So then I asked what about when I add my 106" big bore kit... not a problem the tuner will adjust. So the last phone call, was asking about cams. Surely this would be to much of a change and I would need to do something else. Nope,.. the TV-3 adjusts to anything I do to the bike. Even if I had a prior reflash of the ECU, and a H-D map loaded in, the tuner would adjust for it.
It almost sounded to good to be true, but I thought for $400 I couldn't go wrong.
Install was easy,.. a lot easier then I thought it was going to take. The instructions were not really clear, and I was thankful I had a servica manual to refer to with pictures, so I found the right connectors. Oh yeah, did I mention its plug and play? No splicing, no reading wire schematics and no guessing if its hooked up right. The hardest part about the install, was deciding which color zipties to use. I did take the extra step of sodering the key power wire,.. but they give you the connecters to tie in.
On the road I could tell the difference in power from just the ventilator and the tuner. There was no popping on decel, and Im happy with the results thus far.
Next up I will add the dresser duals. Then later on, put on the big bore kit when I decide which cams I will go with.
So if you have a newer bike, and like me and don't want to hassle with maps and adjusting the fuel/air ratio on your bike,.. get with Dr V Twin and get the Terry Components TV-3.
