Hi All , I've been going round in circles and could do with some help . I had my 02 plate S3 Bam , remapped six weeks ago only acheived 239bhp but 259 lbft torque was expected 269 bhp . No fault codes stored . I have replaced N75 , MAF and DV007p all brand new , then decided to bite the bullet and replace the turbo . Replaced turbo with a refurbed K04 023 and new manifold , pipe werx 3inch down pipe and sports cat . Went back for mapping again today and only acheived 225bhp !! With an over boost fault code found , mappers tell me the boost is'nt making requested . I've checked all pipe work for splits/leaks nothing found , where do i go from here ? Any help apreciated as i'm start to loose love for the beast !!
