Wait, another Dinan loving article. This one from jalopnik.... and I quote,
"Hop on eBay or any BMW forum and you'll see dozens of cheap hacks that raise boost pressure on the twin-turbo 4.4-liter V8 (S63B44Tü for you code nerds). The problem is when the boost is raised, the factory computer freaks out, tripping over itself to correct the fuel mixture, ignition timing, and a host of other parameters. Eventually the angry engine starts throwing codes. At best power is lost. At worst, the $299 black box from BestBMWTUNRES just voided your warranty and broke some very expensive things."
geez... how many of these articles and/or videos are out there?
