^I beg to disagree. I don't know what it's like on other platforms, but Cobb and Vishnu tend to back up the"we've never blown up a car" mantra with empirical data. Just before I joined these forums there was a rumor going around that the PROcede didn't control fueling targets as well as Cobb. Vishnu provided logs and data to prove that their product was on top of the game and silence the naysayers.

Since you're asking for data elements, Air/Fuel Ratio(AFR) targets are an extremely important part of the direct injection game. Do your own research, past threads provided a wealth of information for me which eventually led to me settling on the PROcede. I'm a firm believer that you get what you pay for. The Cobb and PROcede cost about the same, but when you're buying a Cobb you're also paying for fancy marketing (nice website & videos). The PROcede is a no-frills dedicated engine control management system that works flawlessly.
EDIT - You just need to start bugging Shiv to buy himself a N20, so he can start working on a tuning solution once he's done fine tuning the N54/N55 Single Turbo
