I feel like people are pretty smart and able to see through some of these posts. I also realize that it is human nature to want to defend people you feel are friends. The AA fans are feeling like they are being attacked because people are saying their kits don't make the power, etc. The ESS fans are feeling like they are being attacked because people are saying their intercooler design isn't as good or their trap times aren't fast enough, etc.
If you take a step back and examine just the facts, it becomes pretty clear.
At the end of the day, when you are alone in your home deciding which kit to put on your $60K+ E90/E92 that you spent your hard earned money on (and you also don't want any problems with hardware, tune, motor, etc), ESS clearly has the win. People decide with their money. They put their money where their mouth is. Most people have decided that the ESS kit is the most reliable and best designed kit out there for the E90/E92. That is a fact not an opinion.
