I have a few things to say about autothority.
First and foremost look at the dynograph they display for the 330i stock.
Seearch here:

You will discover that top torque is off completly and their stock engine is also pulling way past redline.
How is that for a professional tuner??
I went there once for a dyno - innocent and unaware. Their printer would not print. They did not have access to the web from that computer so they couldn't e-mail the dyno sheets. They did not have a spare disk around. Next day at 4pm Robin finally sent me an e-mail with the dyno graphs - no data sheets, no air/fuel info. Plain squigly lines on something that was supposed to be a graph domain.
I was also dissapointed with the atmosphere in there - 5yr old azn kids putting on fart mufflers for their hondas. This is not a BMW tuner. It's a whatever I can get tuner. Be it honda or porche.
But now I know and they won't see me again.
