[QUOTE="TARM, post: 375577, member: 578"] I figure you know these but figured I would put it down so people that actually take the time to use the search functions can find this info. P0198 is either a bad oil temp sensor or its a short in the wiring or connector going to it. That wiring harness many times is stretched tight so it may have pulled a wire out. P1184 is EOT out of range and likely has to do with the above issue with the EOT sensor. Given tuning takes eot into account it could be part of your issue with how its running. P0475 that is just the ebpv that you deleted when you installed the t4 turbo. You can install a resistor? 470 ohm 0.5-1 amp that can prevent the code but its harmless either way. P0541 just the AIH which again is nothing like the P0475 could be handled the same way. P1690 waste gate solenoid like the other two above same deal. If you think you have a boost leak make a boost tester out of a pvc end cap with a hole drilled in the top of it. Screw a air comp fitting into it. But a popping sound seems more like exhaust side. Maybe a leaking up pipe connection? With a new turbo install you very well may have leaks from both sides boost and exhaust. One place to check could be the down pipe vband clamp to the turbine. If that is not tight or lined up rightt could be leaking and I could se it making a popping sound. [/QUOTE]
