I installed by myself this module and despite the issues with screws the module installation was easy. it could be easier with a visual aid. I'm currently testing this module in gasoline savings and kilometer per litter still not see the saving or the improvement but I can tell that the engine performance has changed, the engine is more still and has a quicker response at low rev. I think the module is expensive for the results seen.
