hi all, i had my S3 on APR stage 1+ for some time. last week i installed a new VWR intake and APR Cooler and went to do some logs. i found everything to be perfect besides one thing. i'm loosing boost between 3500-4500 rpm, while in the same range i get a strange drop in the MAF reading. i'm suspecting a boost leak as my N75 are maxed out at the top but i'm not sure that's the issue. Boost logs: Maf logs: N75 logs: few more things: 1. i had this kind of a drop before the cooler and intake too. 2. i dynod the car before the intake and cooler and saw a 2-3 kgm drop at those rpms also: well? any ideas? where should i start looking?
