Found the turbo waste gate port was 5mm undersize, which resulted in undetected boost creep. So this is what happens if you run 22psi on a tune for 18psi.
Despite this, it managed to finish 2nd in class at a two day national rally, and didn’t actually start running on 3cyl until we entered a hillclimb a couple of weeks later (and let go about 2km in to the first run)
