Hello. Can anyone tell me what is the boost increase on tuned 997.1? stock boost is 14.5. what numbers you see on a tuned ones? on stock turbos? 20 psi?

 

More in the 17 range if you believe the factory gauge

 

there are a reason not to believe it? in regular mode i have 14 psi. in sport mode I have 17lbs. when car is reflashed what boost should I see?

 

Many of the tunes I've seen just turn on the Sport Chrono overboost function so it's overboost all the time so 17 psi all the time. I'm sure there are other tunes that take boost a little higher.

 

So all the decat+tune are 17psi?? what power can be expected from decat+tune?

 

on 91 octane about 70-80 hp with full exhaust + tune.

 

Is it the same with stock exhaust and cats taken off?

 

 

The dashbord only will show a max of 1.2 bar even if you run with 1.4,
The only way to know the exact value is to check with a piwis tester ( max value showed 1.5 bar) or to connect a pressure sensor directly to the pressure line or a cobb accessport can show it.

 

Right,
And to answer the question when tuned for pumpgas boost is about 1,25/30Bar 18/19psi.
