Only good looking and young ones can tune me, LOL.
I didnt buy it after surveyed the tuning disadvantage. A friend of mine had stubbornly bought it and we tried to tuned it before. Later fedup, he gave it to his friend, LOL. It has a requirement, a drop/certain time depends on your model and brand specifications. Dont waste money calling other ppl to tune. You can do it. Only bad thing, after few weeks, you have to tune again, LOL.
