hmm, how can adding unregulated fuel to the intake save on gas? does driving around with your cold start injector running some how make your engine run leaner, I think not.
plus the Previa is injected so the injectors are atomizing the fuel, in addition when the fuel hits the back of the hot intake valve it is vaporized. This device makes no logic to me on an EFI engine.
with all due respect sir I hope you can prove to us that your are not trying to sell something here.
