Finally got back into a Porsche, picked up a 03 Turbo, 4 weeks ago. The first 2 weeks were absolute bliss, the car was a rocket! Then, 2 weeks ago, I drove to the airport (in record time). I parked, went in and picked up a relative, got back to the car, everything was normal until I had enough room to hit the gas and take off. Not a whole lot happend. Car would not go over 0.2 BAR, no CEL errors. Got home, let the car cool, took it out again. First time I hit it, I did get boost but after that first shift, the most was 0.2 BAR. I've had the car out a couple of times since and no boost (0.2 max). The car is anemic. After reading some threads, I disconnected and removed the MAF, I was confident the MAF was the problem...nope. Same issue but this time ABS and PSM CELs, probably because of the disconnected MAF.

The car: 2003 911 Turbo with 25K miles, EVOMS Stage 3: intake, chip, exhaust. I'm new to Nashville and don't know of a Porsche mechanic that I trust yet so I'd like to fix it myself, I've always done fluid changes and brakes on my performance cars. Any advice on what to do next?

Also, if I do end up taking it to a mechanic, any concerns about them resetting the chip to stock?

Thanks in advance for your help!

Check for boost leak would be my advice.

If you do end up taking the car to a mechanic pick one that knows these Turbos inside and out.

Can't imagine a tech re-flashing your car's DME without talking this over with you first but when you take the car in maybe you need to ask about this?

Congrats on the new car..

It sounds like a major boost leak..

Intercooler hose connections..

It's time to pressure check your intake system. Plenty of posts as to how to make a kit..

Thanks for the responses. I'll look into doing a pressure check.
