I need affordable upgrade ecu this is might be the cheapest way if it works.
this guy said it will replace stock fuel chip so I don't need any other board.
but i've been hearing that I need to install piggy back board to install any reprogramed chip.that's why pettit or M2 charges lots of money.

So my questions why 3rd gen ECU need piggy back board for?
this chip gona work without piggyback board at 12-13psi boost?

here is the link.
