I'm not saying VF is bad, on the contrary, I find their kit to be amazing and I am in the process of buying one for my M. However, I'm hesitating due to lack of videos, dyno, vbox, testing charts and all those threads are scaring me away and make me think again about my decision.
Some people are still having issues even after the in house tune(e46 m3), which has kept me scared of their kit :S
Even the eas vf570 z4m is still having tuning issues, I'd like to see just one z4m running strong with videos, idling, cold start, dyno, vbox and then I'm a customer all the way vf570 maf less, stage 2 directly.
