My car literally just hit 20,000 miles last night, it's a 2008. I drive this car like a grandma for the most part, and I only had a JB4 on it for 1,000 miles. I am stock now, and this sound is more than prevalent. Never boosted more than map 1's 13psi
If the cause is truely from overboosting, that's pretty crazy that a car with this low of milage, running only a psi more boost than Dinan is having this issue
