Default Stage 1 boost has returned to stock levels

Have Stage 1 installed for eight weeks
the boost has gone back to stock levels, have
checked every thing.
Called Mopar Ralph will call back A.M.
My wife drives it every day did it learn her driving style?
I'm not pleased.

IS YOUR CAR A MANUAL OR AUTOSTICK?

Is it slower? Colder temps outside do lower boost, as the air is more dense. Goal is torque here, which isn't the same as boost. Total airflow commanded from the controller attempts to remain the same.

It's 45 here in michigan today, my car makes 11 psi.

When I did the install it carried 15.25 pound of boost
to 6000 then droped to 10.5 pounds at the shift,at shift
completion it went back to 15.25 until you let off the loud
pedal.
Torque is down also three turn of the tires at launch.
Yes it is slower!I know it's 45 I live in battle creek, something is not right.
Ralph from Mopar didn't return my call ether.

Just wondering if you have had your PT at the dealership lately and they flashed programmed the pcm? ptgtcb

When I had my oil changed on Friday I asked if flashing the computer would mess up my Stage 1 computer, like for instance fuel management. I was told that it would not take me back to stock.
3BarBoost, MEXICANPT? Truth or fiction?

The dealers do not have the ability to d/l stage1 so they would be d/ling the basic program which would mess up your pcm. This is in my opinion!

Can you describe anything else with regard to your problem? Any fault codes? Did you get a bad tank of gas? I'm baffled why it would suddenly drop off unless you have developed some sort of boost leak, like the SRTforums types keep plumbing their MBC to the BOV line and making it leak - lowering boost.

I can't diagnose with no info.

The wastegate spring will only allow 10-12 psi over 4500 rpm.. This is normal..You can make 18 psi but after 4500 it will bleed to 10-12. Unless you change the gate. Ps, any dealer flash will render you stage I a spare factory PCM....:-(.....(the fuel map will change).

Nothing has changed from the time I installed the kit ever thing was fine until last monday.
I think you are wrong about boost dropping off, because this would carry 15.25 all the way to 5600 and drop off to 12.5 at the shift and once it shifts in to overdrive it would pull until you run out of nerve.
It has lost alot of the torque it had at that time,I have checked every hose and line for leaks and come empty,that's why I the post.
