Almost a year to the day since my supercharger was installed,
I was driving along and felt "no power" from the car.
The car would drive 60mph+, but there was no "satisfaction" when I stepped on the gas over 40.
The car felt like the supercharger was not doing anything.
You all know that you get to know the sounds of your car... Well, my start-up sound seemed to be missing when I started the car.
The check engine light went on briefly, but then cleared.
I sent a text message to Dr Dave at DDMWORKS.
( condensed version of the story... )
He did some diagnosis over the phone, with me taking videos and capturing sounds, and poking around the supercharger.
After 30 minutes, he said that he knew what the problem was, but we needed a boost gauge for a final test.
He sent me one, and we did the last test.
The testing revealed that catalytic converter was acting as if it was clogged up. I could not drive
the car to 5k RPMs. The car would stutter above 4k RPMs. A P0420 code appeared as well.
Other symptoms included a smelly exhaust, and no sound from my Magnaflow muffler. The car sounded like a completely stock NA car.
Dr Dave sent me a previously-owned catalytic converter. I got it installed today. Now my car is running and sounding as a supercharged car should.
The old 'cat' released silver shavings when it was shaken.
...a big THANK-YOU to Dr Dave at DDMWORKS.
