What should the boost level be( psi or bar) for a 2007 997 Turbo with AND without Sport Chrono ? Thanks

 

Pretty sure stock is 11psi/14psi overboost w/ sport chrono.

 

Pretty sure (based on the documentation) it is 1 bar stock non sport = 14.5 psi
And with Sport Chrono Package it adds 10 second overboost of .2 bar (1.2 bar) = 17.4 psi

This is for the 997.1 TT 2007-2009 (OEM - non-tuned/modified)

^ what he said.

 

Kadzooks, that is what my car makes, the previous owner must have flashed it back to stock for the CPO. I've had this thing since July thinking it was running on the EVOMS tune. Man these things must be really fast on a tune, lol.

::hangs noob head in shame::

 

Yes...That could be. I have a Softronic tune and when I use my Torque App and BT OBDII Adapter, I get well over 20 psi...See below from No Fly Zone - Midwest. .Get your tune back!

For those running stock 997.1 - does your car ever hold 17psi/1.2 bar? When in Sport mode, mine will overboost very briefly to 16/17psi, but very quickly (second or 2) drops back to 14/15.

 

I think that is pretty normal for stock. That is what I recall mine doing long ago before the mods began...

I would spike pretty quickly, then typically fade and fall off a bit shortly after. That is by design, and normal for the factory tune.

Yes that is what mine did stock.

 

With a tune you could still be seeing this with supporting mods. More air pushed through doesnt need as much boost to make "loaded power"

And the stock gauge only goes up to 17 so you might be making more. If it pegs at 16/17 and doesnt lower as rpm rises you have a tune.
