I think I have decided to go with a DirectLink tuner. Would appreciate any comments or commentary. I have looked at TTS Mastertune,SERT, and others. The gentleman that will be doing the dyno after I install the Andrews 48h cam in my '09 SG prefers the DirectLink. The only downside I've heard is that I'll have to take it back to the same guy or another tuner using DirectLink product to get it retuned without starting from scratch if I want to do additional mods to the bike. Thanks in advance

 

I had the direct link tuner on my CVO Deuce and really it comes down to the tuner. There is no way to tune yourself or download maps. check your area for tuners using this device so you know you have options if not happy. If you are planning more than cams later I would not go with it as you will need to re tune again and that $$ doubled with one more upgrade. I also had the TTS for my 107 but I really had never planned to do any tuning myself and felt at the time it was the best device for tuning. I currently will be going with the powervision since you get a map pre loaded and its plug and play ( couple of minutes and its done) and free maps as required. It will be close as any tuner can do and I only have to pay for the Powervision once. Its the best deal all around IMHO.good luck with whatever you choose

 

I did the directlink too. Good value for money. Saved a lot in comparison with the SE race tuner.
