so since we can't find the the right GL450 of those left on the lots around the country we are looking to order one this week - my question is that with the new V6TT rated at 362hp what do you all think a tune will bring in terms of hp/tq - and i wonder if a tune will work those turbos too hard pushing a 2.5 ton truck. I am guessing to get the real potential headers may be the key too - i keep telling myself this is a truck and not supposed to be a monster

No one can tell you at the moment since the MY2015 GL450 is the "new" 400 twin turbo engine not seen yet in the US.. I would expect "tunes" will be available from 3rd parties by year end...
