that applys to any old garret turbo that the cossies have
they have only got 3.5k power band
so what ever they "come in at" after 3.5k that they are dead
my t34 came in at 3k it was flat out at 6.5k
same thing if you put a .48 housing on that t34 it will come in quicker but tails off quicker aswell because of the power band
you cant have both ...
