Did you see what OP's most recent reply....While I haven't dynoed anything... I can tell you that when I added the TBS my fuel gauge is dropping much quicker and my driving habits haven't changed. It seems like I'm burning through more gas with it on...
I have about a half a tank and will keep an eye on the avg MPG for a bit. When I'm ready to fill up, I will pull the TBS to see if there is a difference. Keep in mind I don't drive much (work from home) so it may be a bit before posting an update.
