Can you explain why can I NOT get savings from a correctly installed HHO DC at 1.5LPM and a MAP/MAF installed? I use caustic soda NaOH at about 18% solution and distilled water.

My fuel consumption remains about the same (38mpg) and the installation of the MAP/MAF caused an error in my fuel on-board computer and caused my Turbo to fail!

My car only has 70,000 miles on it and it has been mine since new.
