Thanks for the link,
such things are of interest to me.
have heard of guys using small amounts of acetone and some other stuff to do similar.
So far i just been wakin in some injector cleaner every few tanks, half of the bottle to quater tank and the other half next tank.
fancy it works but i could imagine it the car always goes well.
