[@lexleo710]

Where does the white cord go if you have bm3 , do I just cut it off?

[@nose733]

Does it add any HP ? And will this require a tune ?

[@extremepowerhouse8365]

This kit tells you how much Ethanol you have in your mix. It does not add any HP on its own but it allows you to run a more aggressive map with a higher E85 content.
