"It's all fun and games for them till I decline the warranty on their blown engine. I see alot of E90 cases come through here with damaged, or completely blown N54 engines that usually have some sort of aftermarket software (usually a Dinan tune) running higher boost. Contrary to what a lot of people may believe, these motors are already running on the ragged edge out of the box. They can make good power at higher boost levels, but they just do not hold up well."
So does this not apply to E92's or E93? Are you sure this guy is a BMW tech? If so then why does he only mention the E90?
