ok kind of just out of interest tbf but would like to know and could be useful What software and program do they use to remap the standard ECU? how much does it cost and where from whys this any different to getting a standalone? Possibly change ignition advance from looking at knock getting pulled on vag.com when you come into boost? Adding more fuel where needed buy looking at AF gauge on dash to make sure your not running lean. possibly increasing your redline Surly it would be more accurate than a begi even with a noob setting it up someone sent me this link (looks like ebay scam crap
