hi guys, ive been collecting parts for my w202 for a couple of months now and i'm not far off sending her in, however, i have the 'sluggish' 2.0i petrol engine with a manual gear box, i've changed the air filter to a newer one, what should be my first tweaks to get more power and effuiciency out of my engine. its done 130K

thanks, VERY excited about finally becoiming a member, i'm on my second w202 and it took me ages to find it, full leathers esprit in aquamarine blue.
