Cleaned MAF, and car is slow again :(

140/181? if thats what you're refering to is the maf airflow reading in g/s.
181 is roughly 226hp, what mods have you done?

no significant mods other than the chip. how'd you calculate that? it'd be lucky to have 190hp imo

stock 1.8t (150hp) records roughly 120g/s.
120/150 = 0.8, so your reading gives 181/0.8 = 226hp roughly
stock s3/tts (225hp engine) reading is in that range, remember these are not wheel hp. from what i've seen chipped cars usually give about 170g/s and i think these may be k03s cars so im surprised you're getting that high with just a chip on a k03.
