Giachino said:So if I'm understanding this correct, if you have the juice / attitude, essentially it'll waste your stock charger? becasue it surpasses 35psi on any level? Doesnt the thing defuel to prevent that?
I don't think that is what was meant. You can set the max boost at 35psi(default I think) and it will back down when that is exceeded. But that is about as high as I would trust it. I never saw the Juice/Attitude get over spikes of 41psi on the stock turbo even on highest setting. 40psi is not going to nuke the stock turbo. Most other boxes I tried pushed boost to 45psi on the stock turbo. That was actual readings on the Autometer guage. I believe that the Juice/Attitude is one of the safest moderate performance boxes out there. It definately was the best I tried at keeping EGTs down. Just saying that if you stack a pressure box or upgrade turbo, you need a manual boost gauge to know what your boost really is.
