So.. if i do the forced performance compressor wheel upgrade, with the stock turbo, will they know whats up?? the housing should be identical? cause if i cant wiggle out of clauses, ill just do a VF series for double the money, turbo goes bad, then stock goes back in, before any warranty work? Forced performance wants my core before they work on my car, should i tell them to shove it, for 150 bucks?
