You need 3 tanks to see results and will have to replace your fuel filter after it becomes clogged which it will. It cleans the fuel system and carbon putting car up to closer to new specs. Then cold air intake off ebay $30 delivered. Replaced plugs with halo plugs you can get them online search halo. Put 2 spark plug non-foulers drilled out over the oxygen sensor tricks the computer makes it run leaner. Removed the side mirrors and antenna. Stripped the back seat and carpet out if it was bolted down and I didn't need it I removed it and all extra weight. I would like to get another 10%.
