Let me be the only fool that spends 5000 euros on his S3 and loose 16bhp! learn from this. after intaling parts that I have waited mounths to arrive (i am from Romania) I saw on my VDO boost gauge that suddently my BAM S3 is runing 0.7 bar instead of 0.9 that showed in stock configuration. the car in NOT chipped and has only the next addons: 1.APR downpipe 2.Supersprint RACE exhaust 3.Neuspeed intake kit 4.Samco intake pipe + Samco intercooler pipes 5.very light flywheel from Helix clucth kit 6.very light pulley ofcourse that in 5000euro I bought some other stuff(rotors,pads,front bumper,..) but ... so , the other day I dyno the car and it makes 209 bhp and 265 torque. imagine my disapoitment when I saw that, when a freeflow exhaust on my Impreza STI made 39 bhp at the wheels. PS: the car is in perfect condition. everything is ok. was checked by Audi,vagcom,testers, gurus , everybody. what to you say about this?
