I just spoke with a sales rep from Cobb. He said that a flat plate design will not work well with stage 2. He also said that boost creep should not be experienced on the 06 when running catless. He said that should boost creep occur (he said this usually only occurs durring sever cold weather), it can be resolved by simply adjusting the wastegate actuator arm. Sounds like a good argument to go catless. Any feedback?
