Big Gun Exhaust TFI Power Box EFI Tuner

I ordered this for my sons 2019 Honda Foreman 500 Rubicon. As reading the installation directions it told me to how to install the O2 delete but it was not in the package, so I had to call SVS powersports and ask did my model have a O2 delete they explained no that the main directions are generic for all the models. It would be nice if directions were model specific, I would not have had to make a phone call to ask this question. The part itself was worth the money and paired with the Big Gun Evo U exhaust gave my sons four wheeler a little more horsepower. Easy installation!!
