My truck is stock as a rock except for the smarty, intake and exhaust. I just ran the tnt on 9 and all I could get it to build was 45lbs. I never touched the wastegate or anything to see if I could make it build more because I didn't want to blow a HG or anything. I may have a boost leak, or maybe I could have adjusted the boost elbow to make it build more, idk. I just thought that the tnt on 9 just wasn't enough fuel to make it build anymore than 45lbs, so I never fooled with it.
I don't beat on my truck much at all, so this turbo has had a very easy life. I still have the original box and packaging material from II so I will ship it out like that.
