Would you like to have full control of your EFI system, freedom to make major or minor engine changes or tuning adjustments without a master’s degree in electronics and computers? Here is a simple solution—ThunderMax® with Wave Tune AutoTune! The ThunderMax® is a completely new product that replaces the factory electronic control module (ECM), not an add-on box or post-fuel signal modifier. The ThunderMax® is purpose-built to deliver uncompromising performance with advantages not possible with post-fuel or flash systems – but you don’t have to be a rocket scientist to install, program or make adjustments to it.
