    Volvo Penta GXi-E Low Power and 2 DTCs

    Volvo Penta GXi-E Low Power and 2 DTCs

    While I cannot be sure it looks like a custom tune, easy enough to happen. Somebody sells a product on eBay stating Volvo ready. Looks like a big mess from here..I'm quite sure penta went to its own software in 02
