I havent really seen a difference in power or gas mileage from the Helix Power Tower. I can say it looks cool under the hood. I would seriously suggest reading the instructions, throwing them away and going at it using common sense and mechanical ability. I was disapointed that I didn't even hear the whistle everyone had talked about, oh well I have probly spent money on worse things!
