my thought was always that it would have effects in old cars...i.e. old engines, old technologies.
Now with ECU calculating and measuring A/F and looking up the hardcoded fuel map why this little gizmos?
Best way is to get your car tuned correctly and also beware of heavy feet.
and I do agree on the statement that if all this thisng works....why the VVTI lar..IDSL lar..DVVT lar...etc..?!
why not the manufacturers just add all this things and save their R&D cost and expenses?!
