And people claimed this was true years ago, now someones saying they can only do it now, and only on BFII's and FG's. This whole thing is a load of sh*t. No one knows wether its true or not because so much crap has been spun about it in the past. Either way, its not hard for them to spot one that's been heavily modified anyway. Injectors, exhausts, intercoolers etc. If you want to modify, just do it, don't worry about this crap. Warranty isn't worth the paper its written on anyway as most dealers do whatever it takes to get out of any form of warranty work, and if they do do it they end up f*cking it up anyway.
