when I was stating 40% duty cycle was to give some information out in by busy schedule. I've compared these turbos to the ebay ones. And I will say there is defiantly a big difference . I applaud Pure because from my personal opinion these are best I've Installed & dynoed. I've installed vtt,rb,pure stg2,ebay, oem.They should def perform better but honestly Alex owning shop doesnt negate misinformation you should be held to hire standard where saying things like 40 percent is not acceptable when influencing peoples money. Obviously the same chra in a cast solution should perform better but these are incremental improvements. Wastegate position can tell you when maxed out but cannot tell you headroom. Their are points out off the compressors efficiency island where more psi can lose power. I personally applaud pure for their naming
but hey I just wanted to chime in to give my quick review how these perform.
