hi all am currently running a forge splitter r valve on my s3 at 16clicks as forge recomend and have noticed it holding off after bout 4500 rpm have had a new maf sensor put in by audi 2 weeks ago so not that used to run fine with old bosch valve am thinking now just putting a forge 007 on instead would it be the valve or something else wrong cheers
