I'm just curious about Boost bottles and what, if any, effect they have on performance and feul milage. DO they really work?
Also, does brand matter? i.e., what's better, an RSR or a Powermadd bottle? They're priced the same.
Thanks

newfie, I checked on this last season, and pretty much everybody I talked to said to save my money. I don't remeber what their reasons where, but didn't get very many positive responses.

they were factory on my vmax,,,,,never ran it without them,,,,,dont know how much it helps,,,,but she has always ran pretty good
