It all comes down to driving habits. Are you the type of person to take it to redline every single time then shift? Are you more conservative and shift at around 3500-4000? Remember.... your car doesn't go from vacuum to 10psi instantly; your car builds boost over the RPM range. If your shifting @ 3500 RPM, your car may only see 4-5psi. Driving habits will determine how long it lasts.
