Zippers Performance Products Dan Fitzmaurice Products do not deliver what they guarantee, they do not stand behind products Elkridge, Maryland

For the last 2 years I have been attempting to enjoy my 2006 Harley Davidson Night Train. While looking for performance parts to upgrade my motorcycle I was introduced The Thundermax Auto tuner by Zippers performance. After hearing what the product does and offers I purchased the product and had it installed.

The details I offer are a direct result of the product not delivering what they say it does. Moreover, the entire Zippers staff points fingers at the patron stating its our fault and the motorcycle has mechanical problems, never owning up to the possibility that it could be their product.

From the beginning when I began experiencing issues with the Thundermax product I would call and speak with tech support. While on hold I listened to their commercials stating; Our Thundermax auto tuner works with any bike and any configuration, no more dyno-tuning your motorcycle.

While working with the Zippers staff they were all friendly and helpful at first. After repeated issues with my motorcycle they began stating it was my motorcycle, no way could it be their product. I was even tricked by the CEO Dan Fitzmaurice, acting a one of the techs. Later on as the issue began to build did he reveal his true identity.

Here are the issues that I had with the product:

• Coughing (Grey smoke)out the intake intermittently
• Popping out the exhaust (not the average popping)
• Loud popping when blipping the throttle
• Sever Reduction in performance
• When idling it sounds like the engine is "hunting" does not have a rhythm.

I have done everything the company had asked of me; spent countless hours attempting to tune the bike with their tech support remotely. Spent over a thousand dollars having my motorcycle diagnosed at several dealerships, including one of their choice.  The motorcycle was given 100% fully functional and mechanically sound each visit. Although Zippers still dangled the carrot stating it had to be my motorcycle.  I researched the issues associated with the Thundermax and this is not an isolated incident. In fact there are several blog sites referencing the same issues.  

I have maintained all of the email correspondence between Zippers staff and myself. Up until the end I had always stated I believed in their product and I wanted nothing for free.  I just want what I paid for to work properly and enjoy my motorcycle.
