Is the added power really from increased boost over 20 PSI or just added power due to more aggressive timing. More boost doesn't always translate to more power. Just would like some clarification.

You're absolutely right. Timing is always adjusted to be at MBT whenever other variables such as boost are changed. Which way you can/should go always depends on octane used.

Thanks Dzenno for your excellent service and honest, thorough advice. Looking forward to installing the 3barTAP sensors and new exhaust and having a custom "ProTuning Freaks" tune on my 997.2 TTS!
