Stage 4 Supercharger.

[RD2CUTMD]

Just had installed Stillen Stage 4 supercharger and having lots of problems with my check engine light coming on. Shorlty after this occurs, the engine starts to run funny and lose power. Can anyone help? Charger was installed by a legit speed shop in baldwin Pk.:flame:

Did the shop tune it after installation? What is the code that the CEL is for?

+1 First you need to scan your OBDII to find out the source of the CEL
Do you here any knock?

Code P1072 Run rich bank 1

The stillen supercharger comes tuned from stillen and your are to step up to a colder plug
it also has a seventh injector that goes on the inlet tube maybe they put in the wrong injector and its blowing in too muchbring it back and have them check it. just my 2 cents

Several possibles. I generally start with the simplest first.

MAF harness plug not correctly seated / loose or broken wire. A bad MAF is also possible. If the code is thrown at high rpm/boost, you might have to clamp MAF voltage to trick it.

Intake air leak -- listen for a hissing sound in engine bay.

Bad O2 sensor (not a high probability) -- swap O2 sensors side to side and see if you get a P0175 code (bank 2).

If you get the code at idle, it's possible fuel pressure is too high -- should read 51 psi at idle.

Still no solution, possible bad injector on 1, 3, or 5. Check injector harness connections. See if one injector is running an odd duty cycle. A really bad injector will likely give a P03xx misfire code as well.

Good info from both Joe and Tere. Let us know what you find out.

Must be nice to be close to Stillen's shop...

Summer time coming up and with 90+ air temps -- I can give you the solution to P213X and P112X codes too. Hint -- high boost and high intake air temps cook electronic circuits.

What numbers are you putting down (before the trouble started, just curious BTW)

[kenpo350Z]

Sounds like they need to reflash the ecu or adjust your air/fuel levels. The only turbo vehicle I had was the Mitsu VR-4 3000GT. It came that way from the factory.

I'm sure the shop that did the work will stand behind it and take care of you. Let us know what happens. I would love to see some videos of the beast when you get a chance.
