And i really dont think Topspeeds testing was propaganda....i mean they dont make anymore money selling a 1.5xtr than they do a 2.5xtr....its just different dynos reading differently. Their DJ seems to read somewhere in the 15-25% range higher than airboy. I had a guy here in SoCal go get on a dynapack with a 20g on meth. he made 330-340 airboy and 420 on the dynapack. its really not that uncommon.
Blouch's site even says this turbo is made for a 2L. My advice to anyone running this on a 2.5L is to put it up for sale and get a 10cm2.5xtr
