Warranty 

Alternative Performance Engineering, LLC offers a one-year manufacturer’s warranty from the date of 
purchase. The warranty applies only to the Flex Boost module, the flex fuel sensor, the included wiring 
harness, and their functionality. Always read the instructions in this user manual before attempting to 
install or use the flex fuel power module.  
 
The warranty does not cover damages caused by improper installation by the buyer or by the buyer’s 
agent,  or  if  the  product  has  been  damaged  by  wear  that  is  not  caused  by  normal  use  or  by  a 
manufacturing defect. Any modification done to the flex fuel power module or wiring harness without 
the consent of the manufacturer voids the guarantee. 
 
If the product has a fault that can be regarded as a result of a faster than normal wear or a result of a 
manufacturing defect, the manufacturer will provide the buyer with a new product or repair the faulty 
product. The manufacturer has the right to redeem the faulty product if it is replaced by a new one. In 
no event shall this warranty exceed the original purchase price of the flex fuel power module nor shall 
Alternative Performance Engineering be responsible for special, incidental or consequential damages or 
cost incurred due to the failure of this product. 
 
The manufacturer reserves the rights to any modifications, expansions, attachments, or improvements 
made by customer.  
 
The use of the flex fuel power module happens at the user’s own risk. The manufacturer commits only 
to  make  up  for  damage  caused  to  the  flex  fuel  power  module,  the  accompanied  wiring  harness,  or 
accessories as covered by the guarantee. 
 
The manufacturer does not make up for damage caused to the car by the use of ethanol containing fuel 
or the use of the flex fuel power module. Neither does the manufacturer make up for damage caused by 
the installation to the product, the installation’s target or the person carrying out the installation, if the 
installation is carried out by the customer or by customer’s agent. 

Returns 

If you are experiencing an issue with your Flex Boost module, please contact us so we can help resolve 
it. If you wish to return the system, all components must be returned in original packaging, in resalable 
condition. The flex fuel power module will be inspected for damage prior to any refund being issued. All 
returns must be made within 30 days from the date of purchase.
