Hey guys,

Just looking to get opinions on using these type of "chips" to get better fuel mileage.... Are they a scam? Anyone ever used one in your van or any other vehicle ?

I don't like mass market chips. go to someone who can program your computer. I would run your van on a dyno and get as much info as you can to provide the programmer. You should have your van dyno'd after the computer is flashed and send the results back to the programmer to see if there is more he can do to it to get it spot on. I know a company PCMforless that does computer flashes.
