How about the power chip, that we put inside the ECU?.....can it Increase throttle response and give better performance for our car?

Only little bit of performance boost. So if its expensive, its not worth it.
Never expect more than a 5Hp power gain.

pm me i'll give u this chip

changed working of acav (+10Nm on dyno at 3500rpm) and rev limiter at 8000rpm (+ some hp on high rpm - it depends what exhaust manifold do u have, cat, airflow filter etc.)

Do you have a dyno run with this chip? The dyno in your topic with 155hp/185Nm was still with standard chip?
