there may be info somewhere else but i couldnt find it... im not real familiar w/ the MEVI, but have heard great things... i hear it goes well when u have a ecu upgrade, but do u need an ecu upgrade for the MEVI to be effective??

also if anyone wants to share any info at all about the MEVI, any knowledge is welcome

 

this link was shared with me when i asked very similar questions so here you go.
