Question about Cars & Trucks
Saab turbo not working drives all right but no boost
This means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow).
A code P0102 may mean that one or more of the following has happened:
The MAF may be disconnected, or a wiring connection may be bad
The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
The MAF sensor may be faulty
The vehicle computer may be faulty (very rare)
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.

you can fit a manual boost tap that fits into the hose from the wastgate solinoid to the wastgate which tricks the wastgate into opening a little later raising the boost pressure, tho i recommend a electronic boost controller as it holds boost better in the higher revs. Be mindful only raise the boost by 2-3 pounds as the more boost you run the hotter the air gets and the more likley it is to start to detonate.

since you have done all that and it does make sense to what you have done,the next step is you have to have fuel to make boost please check your fuel preasure ,

No. Turbo charged engines have been designed to have the turbo. The turbo uses exhaust gas to spin a dual air compressor to push additional air into the intake, without it the car probably won't even run. There are numerous electronics monitoring pressures and temperatures. Sorry turbo has to be fixed for car to run properly.
