So I bought a volo chip for my car. I noticed that it had increased the back pressure- or at least made the throttle a bit 'harder'. I'm not too fond of it and have not noticed definite differences in my fuel efficiency. Anyone have some tricks for this? Should I set up a switch to turn of the chip when I turn off the cell? Or would I then have to wait the amount of time it takes the computer to adjust for the HHO cell to have an effect?

I payed a little less than 100 for it and its pretty easy to install but I would like another method if thats possible without wasting money. Problem is, my car is picky, thats why the Volo chip was the only thing that was really recommended.
