Turbo replace now no power..

[VagrantCain]

Tried searching and did not find anything on this.

I have a 2001 A4 1.8T AWM, stage 1 APR with R1 DV, cat back exhaust, inlet hose, throttle body hose, and running 2.0 coil conversion. My k03s blew and I ordered a k04 replacement. Installed k04 now I have no power, I can hear the DV and the turbo spool but there is absolutely no power from it. It is like driving when the turbo was blown. Pressure tested for boost leaks and only found a couple small leaks which were dealt with and still no power. Any ideas?

your probably getting not enough fuel. our cars with an apr tune don't like k04s without being tuned for them specifically. thats what i know about apr at least. your apr is probably just not sending enough fuel and your probably going to need the jolly green giant injectors too

Well found it! It was my N75.

K04 runs fine with a tune for the stock turbo. Just slightly lean, but the ECU will compensate.
