'02 Chev. Impala, 3.8L

Thanks Nick in Tech. Support,
I have definitely gotten the promised 25% increase in my fuel economy on my '02 Chev. Impala, 3.8L. I really want to thank you for your fantastic support in helping me figure out how to install the system. Your rapid phone response and "walking me through" the corrections made this installation of the AquaTunePlusquick and easy.
 Best regards.
Jerry G.
