Okay, I've had 4 re flashes on my truck to supposedly fix the issues with the troubled flexfuel program. None have worked, SURPRISE! When I call to find out how Toyota plans to fix this ongoing problem they tell me they have had no returns on trucks they have reflashed, except for mine. I personally find this hard to believe given the performance after about 4-5 refills. Rough starts, poor gas mileage, decrease in power and performance. So I ask you, my fellow flexfuel owners, has it worked for you?
