while we are on the subject of .09 My 06 was running at full .1 i just installed the spt intake and cat back exhaust. now i am only running at .09. The butt dyno says its slower too. I donno maybe that is psychosomatic. how hard is it to cause leaks while installing the exhaust?
 
^^ Could be a leak. Did you reset your ECU by disconnecting the battery and pumping the brakes several times?? If not, you need to do that and then restart the car (it will take several seconds of the engine turning over to start after resetting the ECU) and let it idle for a minute or so without the A/C on and then go take the car out and hit max boost a couple of times.

I just had the SPT Catback installed yesterday and am experiencing the same thing on my 05. Before the catback I was completely stock and used to hit ~.1 MPa.

Now it reaches a max of .09 MPa, butt dyno feels the same. The dealer said that they reset the ECU for me and I attempted to do a few WOT runs as I left the dealer, but there was too much traffic.


EDIT: Did your's have the "SPT" logo on the tip? I just noticed that mine has no logos on the tip. No big deal, just wondering.
