Wish I could let you know. I have one but have yet to run it. Have the same type they put in the twin turbo lingenfelter vettes. Damned thing better run good. They cost enough, lol. Not sure what stall you are going for but mine was 3600 but we restalled it to 3400 for my smallish turbo. They said they could raise it to whatever also.
Enough of my rambling, TTT for you. Would like to know myself
