I do not see where the addition of a SERT will buy anything but more $$$. The ThunderMax set up has different levlels of AutoTune that you can adjust to have the sytem learn faster etc.

Granted a SERT may be able to help extract extra HP & Torque but will it be worth the $$ and will it be that much more HP& Torque?? The other factor is that the AutoTune products tune your bike for the way you drive. Now if you drive WOT all the time then a dyno tune may be theway to go. Just hope you have the $$$ for all the attorney fees and court costs.

BTW the tuners around here are making extra $$$ because my Autotuned 88 is eating the 95's & 103.

I have a 2007 ULTRA with Stage I air cleaner and V & H true duals. I will be adding other performance products in the future, i.e. cams, big bore, etc. Has anyone tested the Daytona TwinTech vs. Thundermax Auto Tune systems? Where is the best place to purchase?
