hi there...
friend of mine from this forum 911lover is having some trouble with his 997T PDK... his car is ECU tuned and he never had any kind of problems... BTW his car is a monster...

recenlty he did some new upgrades and bought FABSPEED HEADERS AND FULL EXHAUST... when he changed the pipes his car was showing a TURBINE SENSOR PROBLEM, somehting was a recall there in USA from what i now..

he changed this sensor when changed the exhaust did all together..

AFTER that, his car now cant go HIGHER than 305km/h(speedo) its something like a REV LIMITER at around 5500RPM at 6th gear...

BEFORE THIS last changes, with ONLY THE ECU TUNE, his car could reach EASILY 335km/h SPEEDO...

So what you guys think? the exhaust and headers seems well installed no leak or something...

any idea... maybe the other turbine sensor can be bad too??
the strange think about this is that his car is not showing any kind o problem in the computer...

thanks for any feed back
