Sounds like a boost leak. You need to pressure test

If it started after the turbo install bring it back to the shop and tell them to fix it for free

After they have to tell the next generation of n00bs the same thing over and over.

Don't take it personally Imola - we've all been there at one point or another. I'm actually surprised Rolled didn't ask you to pull codes, speaking of which, you should really pull codes.

Well, your CEL flashing means that your motor is misfiring badly, to the point that you probably shouldn't be driving the car to avoid further damage. Also, what mods do you have if any, and how many miles are on the car? Did you order one of the ebay vagcom cables? if so the software is free but you will only be able to use some of the functions and only the older version will work. go to ross-tech.com and download the version that is for third part cables, I believe its version 409, dont bother registering for it. Connect it to your car, go to the engine module and click Fault Codes, It wont tell you what the codes mean but you'll be able to search for them and also post back here. You could also go to autozone and have your codes pulled but that will often only tell you the codes that set the CEL and wont show you the ones that are intermittent which are important to know about also.

Let us know what the codes are and we'll be able to give you better direction.

I can't see your MAF being responsible for a flashing CEL. As CT said, please post a full list of Mods and details about the car. Also, any specifics regrading your turbo swap would be helpful: did you upgrade or just put in new k03's? Rebuilt turbos or fresh from the factory, etc.
