I have a 1997 Jetta TDI, originally had a 1Z (not AHU) engine and a couple weeks ago I dropped in a good running ALH with the stock wiring harness. Used the ALH IP swap wiring and figured out how to wire the crank position sensor myself, so it should be running like a stock 1Z. Engine is a bone stock manual ALH, 10mm pump with 0.184mm nozzles and a K14 turbo off an AAZ since my GT15 was worn out. I've been chasing down all the usual culprits for low power to no avail. Intercooler pipes all connected, N75 working, all lines routed correctly and not leaking, new line from intercooler piping to ECU and I replaced the section inside the ECU today too. I don't have VCDS to check but I unplugged the MAF to get a freeze frame on a normal scan tool and only saw 39 inHg manifold absolute pressure at 98.8% TPS and over 2300 rpm. Disconnecting wastegate doesn't do anything, and I don't have any black smoke. Only things I haven't been able to try yet are a different turbo or a different MAF. Going to talk to a local VW tech and see when i can get him to verify injection timing and quantity, though it should be fine since I was daily driving the MK4 the engine came from and it ran well. Any ideas?
