Ford E450 305 HP power increase - Banks Engineering

Thanks for all the replies. It is interesting that when we looked at the Banks website, it stated that the upgrade was not available for vehicles in California. When we asked someone at Banks about that, she stated that they would install for us but we would have to be willing to accept that we are "bending the rules." Spending $4,000 on the upgrade and then not being to pass smog inspection definitely an issue.
