Notes
Notes
- This turbo must only be operated with tuning that uses stock Minimum and Maximum Vane Position tables. Failure to do so can lead to excessive exhaust pressure and boost, which may shorten the life of the turbo or engine and may void the turbo warranty.
- Damage caused as a result of non-stock vane position tuning modifications will be the responsibility of the owner.
