This isn't the first time this talk comes up, so could you please answer following:
1) PP-Performance is an Arabic tuning company, right?
2) Has PP-Performance unlocked any M5 F10's speed limiter?
3) Post a video of a stock vs PP-Performance Stage VIP/VIP Plus/President/United Nations that you guarantee someone who pays can expect
I don't think you'll impress anyone with "ask Manhart racing who is the fastest !!111" talk, because nobody cares. Show some videos and 0-100 km/h, 0-200 km/h, 0-300 km/h, 100-200 km/h, 1/4 mile, 1000 meters and stock vs tuned videos because that is the ONLY thing that matters.
