Engine shutting off when TIP is attached

[JackOfAllTrades]

I recently installed a used turbo and the car is running fine and smooth, but when the TIP is on the air intake it will start fine, but after a few seconds or if I hit the gas it'll shut off, but with the TIP is off It still runs fine and it doesn't shut off

What year A4?

Most likely a MAF or air intake issue before the turbo, due to an intake leak.

Check to see if your MAF is possibly put back backwards. Or if there is a leak on the intake box. Check electrical connections and clean sensor element. Boost leak TIP to around 10psi to inspect for leaks.

If no change after that, log your MAF for g/s intake. At this point, I would say your MAF is shot. You want to confirm this first, though through logs.

It's a 04 6 speed Quattro
