Ok. So I have 55k miles on Stage II. No problems. The OEM clutch can't hold the TQ so there is a little energy bleed off until the clutch is replaced.
So far, the tranny has held up. I would suspect 4th and 5th to have issues first. The boost is max before 3k. These gears may not take it under abuse.
There is no up pipe. The turbo is immediate after the header. Very little turbo lag, stage I and II are terrific daily drivers.
One or two have snapped a half shaft; tranny held up fine. Maybe one has had a rear diff issue.
So overall, mod away and enjoy. From a group perspective, failures are few.
