hi,
i have a mk2 jetta with a aaz td engine with t2 turbo. im trying to get some more power by upping the boost and fuel so i added a dawes device to control the boost but even with it screwed in full boost is not increasing its still at 0.7bar. there is no bov fitted. if i turn the fuel screw a quarter turn more will that help increase the boost? i have googled and searched site for answer but cant find an answer. Any help much appreciated
