      So, if we take off the timing set on the ECU, what else can change this?
      For example, with a stock ECU, how can the ignition timing be off? Is there a way?

      The only way I can imagine this happening is if the timing belt was off by some teeth. The ECU will pull timing for safety reasons sometimes, but other than that it should be very accurate.

      Can I have some teeth off and not hit the valves?

      Can my timing be off due to this?

      i've heard of cases where you can be a tooth off and bend a valve but not be totally screwed. it will still run just very choppy and ****ty. i'd take a look though and replace a valve or 2 if needed.

      Just checked the timing marks, and all line up correctly. So, I'm good on the timing belt.
      I have a fahooked MAF, so it could be related to that, as I don't have any measurement besides it for the turbo pressure and what not.
      I will have it changed and see if it gets better.

      that graph looks good.... but i know from your previous post that it feel sluggish past 5500 or 6000, but the log you showed look good... even the knock regulation is within safe range.... i have a friend currently running a vr6-turbo swap 91 corrado.... the logs shows everything is ok, but the cars idle is very poor and the a/f is horrible unless your at WOT & Boost... otherwise always rich with dips to lean..... its coming down to wiring to the maf and knock sensor..... the code we get is knock sensor to low and maf signal low.... it feels like the car is running on its base maps, b/c weather the maf is plugged in or not we are seeing the same readings on the runs... Im just explaining all this to say your logs looks fine unless im missing something and there is obvisouly something not yet checked that is causing this problem....

      Eheheh, from there to Lisbon and then Cascais you would pay something like 1000$ (2 way trip) hehehe

      Well, if the MAF is unplugged, it will show MAF readings?
      I don't have any VAGCOM errors, so it's hard for me to narrow it down. I had a MAF too low reading, which was a wiring issue, but we resolved it!
      Humm, will have to dig into it.
      THanks for the tip!
