Have you tested yet?? PLease let us know.I just read the 44 pages!!!
Too many people that try it and noone has a wideband to check what is truth???
You try to understand from the plugs!!! Just go to a tunner and borrow a wideband!!
We still don't know if it change the cyllinders... if it change with rpms.. if it changes only idle..!
All people said that there is improve but nothing sure.
Ofcourse the guy that went to the dyno he didn't see any difference as their air/fuel was ok so there isn't any need for tunning.
When I will go back to home(two weeks), I will fit the wideband from my car and I will tell you exactly what this adjustments do!!
