Well said.

Another thing to consider when purchasing - I have had a chip kill a stock ECU this past summer. Car ran fine for months, then all of the sudden while driving down the interstate, it died. Turned out that the chip killed the ECU (poor quality chip, but done by a professional shop a couple of years ago). It is very expensive to replace.

Personally, I generally like to run standalones. With the AEM, I got the bonus of TC, 2step, N2O control, etc.
