Try below, this might help;
Start ure car and push the accelerator paddle till RPM is at 3, keep it at 3 for about 30 sec.
Then move ure car in fist gear and take it up till 2.5k rpm. After reaching 2.5 RPM, release the paddle till car is on 1 RPM. Dont change the gear.
Repeat this 3-4 times and that’s it.
Inaddition to this change ure air filter to KN performance filter, even guard will give better result then OEM.
