[QUOTE="steedspeed, post: 589463, member: 4952"] We did get testing done but the tester turned out to be a little less than truthful with us and everyone else. I have actually sent out several "free" sets of manifolds to get testing done from a variety of installers. I figure a set of manifolds counts as enough "manning up" considering the amount of time and money I have to put into them. Results from the manifolds have been very good. It would seem that the manifolds are able to outperform the VGT turbos as the turbos appear to be restricting performance. Judging from the Elite dyno charts, Boost goes substantially higher with my manifolds but without a wastegate the turbos choke the engine and kill the power. [/QUOTE]
