I seen it in summits mag, i don’t know if it really does 25%.
I was trying to find some reviews on them but came up with nothing.

pointless …

I already have the timing jacked up in your car … thats all that box really does

don’t waste $300 dollar on that.

:tdown:

take everyone out to lunch for 300 bucks would be better…

About as useful as eBay “powerchips”, and “MPG boosters” for yet even more cost.

pretty much what i figured, just double checking I was thinking on the right track.
I’ll stick to the basics air/fuel in exhaust flow out.
