ProTuner and HHO

RFQ Details

As an experienced person in the use of HHO systems I recently installed a self assembled HHO system that I upgraded for my older system from a different car. I face the same problem you are writing about which is the lack of car computer adjustment to modify gas consumption having HHO supplement. I found your site and wonder if you can help me individually. My vehicle is a 2005 Toyota Corolla. Please let me know how much the shipment cost. Thank you and best regards, My Ilan Bar Shalom Israel.
