Get the codes read to see where the problem lies. Upgrading the turbo without a tune will not shut the engine down. It won't run to it's full potential but it will run. If you know someone with a VAGCOM cable, you can get a real good look at the system functions.

Check in at AudiWorld.com and Audizine.com to see if someone with a diagnostic cable is near you.
I got the codes pulled cuz I am a mechanic at pep boys but I am not formiliar with Audi. Most the codes had to do with the bank 2 O2 sensor missing cuz I have a straight pipe on it.
Different injector orifices may be in order, or Switch it back.
With a bigger turbo the air/fuel mix could be off. Need more gas with the more air.
