Has anyone done any actual testing on the 04 system?
I see Racetronix really doesnt have anything for the 04 except the basic walbro kit. Im wondering if there are any issues with just replacing the walbro such as pickup issues below 1/4 tank? |
I don't see why there would be too much of an issue below a quarter tank. The vettes have dual tanks, one large, one small. The small tank is always filled so you don't have starvation during hard launches or cornering.
