Any thing that is causing it to be slow can be repair and there is nothing wrong with the Vmac.But you can chance it by replacing the fuel pump and injector lines.If i was going to do this i would call manders 952 4691899.Talk to them and tell you are looking for a 350 HP chance over and he can tell you and should have what you want in used parts. I am running one now myself.

I agree call Manders but the phone number is 800-469-1800 ask for Bill
