well by resetting the ECU you let the car reconfigure for the new mod that you have done for your ride.. You simply go to the Fuse box under your hood and pull the ECU Fuse..leave it out for like 5-10 mins...Then reinsert the fuse and,don;t touch the accelerator at ALL, start your ride....
Let it idle for like 7-10 mins and it should then be reset and help w/ the new mod...
Also w/ changing the filters and plugs you should feel a little diff as you will be giving your ride a better spark to react to....
