    A fantasic ECU
  

*by A***R on Reviewed in the United States on September 11, 2019*

This ThunderMax ECU has my 2008 FLSTSB running like a dream.  The vender was fast, real fast.  If I could give higher than 5 stars to both the vendor and manufacturer I would.

### ⭐⭐⭐⭐⭐ 







  
  
    But I did love the price
  

*by E***T on Reviewed in the United States on August 2, 2016*

I haven't installed it yet, and have high expectations. But I did love the price. Saving almost $250 from manufscturer's price.

### ⭐⭐⭐⭐⭐ 







  
  
    just get it
  

*by I***0 on Reviewed in the United States on June 22, 2016*

I don't normally do reviews but before I purchased this I did a lot of searches for reviews on this and could not really find anything posted much after 2014. I have a 2009 CVO and unfortunately that meant pulling rear tire, fender, and guards to get to ECM. (I am told I am the lucky guy in the world all the others are basically under the seat) I therefore took mine to Harley to have them do it. (they charged me about what the unit itself cost...ripoff). Only had the bike back a few days and WOW!!! Power galore when you want it, no back firing thru exhaust, AND my hands used to fall asleep from the vibration but not anymore as this has smoothed the bike out by at least 60% or better. It is like a whole new Better bike! Don't really mind Harley overcharged for the results I have as it is well worth the results I Got. Hope this newer review helps someone else out as I was really worried about not finding reviews and taking a chance.
