I have used a V&H Fuel Pac for 6 to 8 months and was happy with performance but not with the heat issues we have on Tri Glides. I changed the sprocket to a 30 tooth on my 2010 and decided to try the Master Tune TTS. The performance has stayed near the same (seat of pants est.) but the heat has dropped by quite a bit. I ran somewhere between 250 and 275 degrees before and now I am down around 230 to 240 oil temp. I was also able to adjust my speedometer to equal my GPS speed as it was off after the sprocket change. Very happy with the TTS!!<img src="images/smilies/thumbup.gif" border="0" alt="" title="" class="inlineimg" />
