This weekend I put in new coil packs, plugs, variocam brackets (one was broke), changed oil, filters, etc. I noticed a few things since doing this. First the car sounds a ton better during cold start now with 5w40 Rotella T6, before it rattled kinda sounded like loose exhaust during initial start up. Now it is quiet. Secondly I am getting more boost pressure then before. I am at high altitude (7800') and it is hot 95 degrees. In third and fourth gear pulls I am getting .8/.9 bar consistently, from what I read online I was expecting to only be getting .6-.7 bar (which is what I got before the servicing), maybe less at altitude? I am asking because I wanted to know if there is something that can be wore out and causing me to get extra boost and need servicing, or if it could be tuned? I would think if it was tuned it would go a little higher but not too familiar with these yet.

thanks, Matt

edit - From what I can tell the rest of the car is stock without any performance upgrades - 6MT

0.8 is possible, and spikes to 0.9, but not sustained.
