I just installed this firestorm.. N i say it works beautifully on my Levin..
I think in some engine, it works but not in others.. Why?
It's just science.. Some engine design, burns fuel efficiently.. So, anything extra does not give any improvement
Some engine design have flaws n didn't fully burn d fuel.. This kind of engines need something like firestorm
Well.. That's only my opinion

Oh.. Forgot to mention..
Product knowledge of d seller must be very good.. If not, terrible things will happen
I buy d product from a friend. He tell me to plug it in AM2 fuse..
I check my fuse.. AM2 is 30A.. & also different type of socket..
So, i ask around n google for answer
AM2 is actually for alternator.. So, if u plug in there, all electrical things in d car will be over-voltaged
If u have a voltage stabilizer, it would cancel d effect..
I put in IGN fuse.. Which i think is d right thing to do..
my opinion only
